Description of business and significant accounting policies and practices [Abstract]
Description of business and significant accounting policies and practices	Description of business and significant accounting policies and practices. Texas Instruments (TI) designs and makes semiconductors that we sell to electronics designers and manufacturers; about 80,000 customers all over the world buy our products. Basis of Presentation - The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. (U.S. GAAP) and on the same basis as the audited financial statements included in our annual report on Form 10-K for the year ended December 31, 2010. The consolidated statements of income, statements of comprehensive income and statements of cash flows for the periods ended June 30, 2011 and 2010, and the balance sheet as of June 30, 2011, are not audited but reflect all adjustments that are of a normal recurring nature and are necessary for a fair statement of the results of the periods shown. The consolidated balance sheet as of December 31, 2010, presented herein is derived from the audited consolidated balance sheet presented in our annual report on Form 10-K at that date. Certain amounts in the prior periods’ financial statements have been reclassified to conform to the current period presentation. Certain information and note disclosures normally included in annual consolidated financial statements have been omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Because the consolidated interim financial statements do not include all of the information and notes required by U.S. GAAP for a complete set of financial statements, they should be read in conjunction with the audited consolidated financial statements and notes included in our annual report on Form 10-K for the year ended December 31, 2010. The results for the three- and six-month periods are not necessarily indicative of a full year’s results. The consolidated financial statements include the accounts of all subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. All dollar amounts in the financial statements and tables in the notes, except share and per-share amounts, are stated in millions of U.S. dollars unless otherwise indicated. Acquisition Cost - During the first six months of 2011, we incurred $15 million of acquisition-related expenses ($13 million for the second quarter) associated with the announced agreement to acquire National Semiconductor (“National”). Use of Derivatives and Hedging - In connection with the issuance of long-term debt in May 2011, as more fully described in Note 3, we entered into an interest rate swap designated as a hedge of the variability of cash flows related to interest payments on the variable-rate portion of the debt. Gains and losses from changes in the fair value of the interest rate swap are credited or charged to accumulated other comprehensive income (AOCI). We also use derivative financial instruments to manage exposure to foreign exchange risk. These instruments are primarily forward foreign currency exchange contracts that are used as economic hedges to reduce the earnings impact exchange rate fluctuations may have on our non-U.S. dollar net balance sheet exposures or for specified non-U.S. dollar forecasted transactions. Gains and losses from changes in the fair value of these forward foreign currency exchange contracts are credited or charged to other income (expense) net (OI&E). We do not apply hedge accounting to our foreign currency derivative instruments. We do not use derivatives for speculative or trading purposes. Fair Values of Financial Instruments - The fair values of our derivative financial instruments were not significant at June 30, 2011. Our investments in cash equivalents, short-term investments and certain long-term investments are carried at fair value and are discussed in Note 6. The carrying values for other current financial assets and liabilities, such as accounts receivable and accounts payable, approximate fair value due to the short maturity of such instruments. The fair value of our long-term debt approximates the carrying value. Accounting Standards Adopted - In October 2009, the Financial Accounting Standards Board (FASB) concurrently issued the following Accounting Standards Updates (ASUs): Ÿ ASU No. 2009 - 14 - Software (Topic 985): Certain Revenue Arrangements That Include Software Elements. This standard removes tangible products from the scope of software revenue recognition guidance and also provides guidance on determining whether software deliverables in an arrangement that includes a tangible product, such as embedded software, are within the scope of the software revenue guidance. Ÿ ASU No. 2009 - 13 - Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements. This standard modifies the revenue recognition guidance for arrangements that involve the delivery of multiple elements, such as product, software, services and support, to a customer at different times as part of a single revenue generating transaction. This standard provides principles and application guidance to determine whether multiple deliverables exist, how the individual deliverables should be separated and how to allocate the revenue in the arrangement among those separate deliverables. We adopted these standards in the first quarter of 2011 by applying them on a prospective basis to revenue arrangements entered into or materially modified beginning January 1, 2011. The adoption of these standards did not have a significant impact on our financial position or results of operations. New Accounting Standard Not Yet Adopted - In May 2011, the FASB issued ASU No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS. This standard results in a common requirement between the FASB and the International Accounting Standards Board (IASB) for measuring fair value and for disclosing information about fair value measurements. While this new standard will not affect how we measure or account for assets and liabilities at fair value, the disclosure requirements will be required for interim and annual periods beginning January 1, 2012. There will be no impact to our financial condition or results of operation from the adoption of this new standard.

Losses associated with the earthquake in Japan	6 Months Ended
Losses associated with the earthquake in Japan	Jun. 30, 2011
Losses Associated with the events in Japan [Abstract]
Losses associated with the earthquake in Japan	Losses associated with the earthquake in Japan. On March 11, 2011, a magnitude 9.0 earthquake struck near two of our three semiconductor wafer manufacturing facilities in Japan. Our manufacturing site in Miho suffered substantial damage during the earthquake, our facility in Aizu experienced significantly less damage, and our site in Hiji was undamaged. We maintain earthquake insurance policies in Japan for limited coverage for property damage and business interruption losses. Assessment and recovery efforts began immediately at these facilities. Our Aizu factory recovered first and has been in production for most of the second quarter. Our Miho factory was shut down through the first half of April, then ramped steadily through May and the first part of June. Our production loadings, based on wafer starts, were nearly back to full capacity by the middle of June. There will be a few months of lag between when we start a wafer and when those products ship to our customers due to the manufacturing cycle time. During the first half of 2011, we recorded total expenses of about $80 million (about $50 million for the second quarter) based on the costs of property damages incurred and costs associated with business interruption, net of proceeds from ongoing insurance claims. Almost all of these costs are included in Cost of revenue in the statement of income and are reported in our Other segment. These costs include the underutilization expense we incurred from having our manufacturing assets only partially loaded, costs related to the recovery teams that have been assembled from across the world and other costs. To date, no proceeds from ongoing insurance claims have been recognized related to amounts for business interruption or associated lost profits. We have yet to determine the final total losses attributable to the earthquake. It is reasonably possible that the final losses may exceed the limits of our insurance policies. We are in discussions with our insurers and their advisors, but at this time, we cannot estimate the timing and amount of proceeds we will ultimately receive from these policies.

Valuation of debt and equity investments and certain liabilities

Valuation of debt and equity investments and certain liabilities.

Debt and equity investments

We classify our investments as available-for-sale, trading, equity method or cost method. Most of our investments are classified as available-for-sale.

Available-for-sale and trading securities are stated at fair value, which is generally based on market prices, broker quotes or, when necessary, financial models (see fair value discussion below).

Unrealized gains and losses on available-for-sale securities are recorded as an increase or decrease, net of taxes, in AOCI. We record other-than-temporary losses (impairments) on available-for-sale securities in OI&E.

Changes in the fair value of debt securities classified as trading securities are recorded in OI&E.

We classify certain mutual funds as trading securities. These mutual funds hold a variety of debt and equity investments intended to generate returns that offset changes in certain deferred compensation liabilities. We record changes in the fair value of these mutual funds and the related deferred compensation liabilities in selling, general and administrative expense.

Our other investments are not measured at fair value but are accounted for using either the equity method or cost method. These investments consist of interests in venture capital funds and other non-marketable equity securities. Gains and losses from equity method investments are reflected in OI&E based on our ownership share of the investee’s financial results. Gains and losses on cost method investments are recorded in OI&E when realized or when an impairment of the investment’s value is warranted based on our assessment of the recoverability of each investment.

Details of our investments and related unrealized gains and losses included in AOCI are as follows:

As of June 30, 2011, and December 31, 2010, the majority of unrealized losses included in AOCI were associated with auction-rate securities classified as securities that are available-for-sale. We have determined that our available-for-sale investments with unrealized losses are not other-than-temporarily impaired as we expect to recover the entire cost basis of these securities and we do not intend to sell these investments, nor do we expect to be required to sell these investments before a recovery of the cost basis. In the second quarter of 2011, we recategorized certain auction-rate securities from an available-for-sale classification to a trading classification as we intend to sell them.

For the six months ended June 30, 2011 and 2010, the proceeds from sales, redemptions and maturities of short-term available-for-sale securities, excluding cash equivalents, were $1.62 billion and $1.80 billion, respectively. Gross realized gains and losses from these sales were not significant.

The following table presents the aggregate maturities of investments in money market funds and other debt securities classified as available-for-sale at June 30, 2011:



Due	Fair Value

One year or less	$	5,826
One to three years	247

Fair value

We measure and report our financial assets and certain liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

The three-level hierarchy discussed below indicates the extent and level of judgment used to estimate fair value measurements.

Level 1 - Uses unadjusted quoted prices that are available in active markets for identical assets or liabilities as of the reporting date.

Level 2 - Uses inputs other than Level 1 that are either directly or indirectly observable as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active. Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data. Our Level 2 assets consist of corporate obligations, some U.S. government agency securities and auction-rate securities that have been called for redemption. We utilize a third-party data service to provide Level 2 valuations, verifying these valuations for reasonableness relative to unadjusted quotes obtained from brokers or dealers based on observable prices for similar assets in active markets.

Level 3 - Uses inputs that are unobservable, supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models that utilize management estimates of market participant assumptions.

Our auction-rate securities are primarily classified as Level 3 assets. Auction-rate securities are debt instruments with variable interest rates that historically would periodically reset through an auction process. These auctions have not functioned since 2008. There is no active secondary market for these securities, although limited observable transactions do occasionally occur. As a result, we use a discounted cash flow (DCF) model to determine the estimated fair value of these investments as of each quarter end. The assumptions used in preparing the DCF model include estimates for the amount and timing of future interest and principal payments and the rate of return required by investors to own these securities in the current environment. In making these assumptions we consider relevant factors including: the formula for each security that defines the interest rate paid to investors in the event of a failed auction; forward projections of the interest rate benchmarks specified in such formulas; the likely timing of principal repayments; the probability of full repayment considering the guarantees by the U.S. Department of Education of the underlying student loans and additional credit enhancements provided through other means; and, publicly available pricing data for student loan asset-backed securities that are not subject to auctions. Our estimate of the rate of return required by investors to own these securities also considers the reduced liquidity for auction-rate securities. To date, we have collected all interest on all of our auction-rate securities when due and expect to continue to do so in the future.

The following are our assets and liabilities that are accounted for at fair value on a recurring basis as of June 30, 2011 and December 31, 2010. These tables do not include cash on hand, assets held by our postretirement plans or assets and liabilities that are measured at historical cost or any basis other than fair value.

Contingencies	6 Months Ended
Contingencies	Jun. 30, 2011
Contingencies [Abstract]
Contingencies	Contingencies. We routinely sell products with an intellectual property indemnification included in the terms of sale. Historically, we have had only minimal, infrequent losses associated with these indemnities. Consequently, we cannot reasonably estimate or accrue for any future liabilities that may result. We accrue for known product-related claims if a loss is probable and can be reasonably estimated. During the periods presented, there have been no material accruals or payments regarding product warranty or product liability. Historically, we have experienced a low rate of payments on product claims. Although we cannot predict the likelihood or amount of any future claims, we do not believe they will have a material adverse effect on our financial condition, results of operations or liquidity. Consistent with general industry practice, we enter into formal contracts with certain customers that include negotiated warranty remedies. Typically, under these agreements, our warranty for semiconductor products includes: three years coverage; an obligation to repair, replace or refund; and a maximum payment obligation tied to the price paid for our products. In some cases, product claims may exceed the price of our products. From time to time, we also negotiate contingent consideration payment arrangements associated with certain acquisitions, which are recorded at fair value. We are subject to various legal and administrative proceedings. Although it is not possible to predict the outcome of these matters, we believe that the results of these proceedings will not have a material adverse effect on our financial condition, results of operations or liquidity. Discontinued operations indemnity - In connection with the 2006 sale of the former Sensors & Controls business, we have agreed to indemnify Sensata Technologies, Inc., for specified litigation matters and certain liabilities, including environmental liabilities. Our indemnification obligations with respect to breaches of representations and warranties and the specified litigation matters are generally subject to a total deductible of $30 million and our maximum potential exposure is limited to $300 million. We have not made any indemnity payments related to this matter and do not expect that any potential payments related to this indemnity obligation would have a material adverse effect on our financial condition, results of operations or liquidity in future periods. Acquisition reverse termination fee - In connection with our recently announced agreement to acquire National, if we are unable to close the transaction due to our inability to obtain the remaining regulatory approval, we may be required to pay National a reverse termination fee of $350 million. In addition, we would be required to redeem the fixed-rate portions of our long-term debt (see Note 3).

Gains and losses from changes in the fair value of the interest rate swap are credited or charged to accumulated other comprehensive income (AOCI). We also use derivative financial instruments to manage exposure to foreign exchange risk. These instruments are primarily forward foreign currency exchange contracts that are used as economic hedges to reduce the earnings impact exchange rate fluctuations may have on our non-U.S. dollar net balance sheet exposures or for specified non-U.S. dollar forecasted transactions. Gains and losses from changes in the fair value of these forward foreign currency exchange contracts are credited or charged to other income (expense) net (OI&E). We do not apply hedge accounting to our foreign currency derivative instruments. We do not use derivatives for speculative or trading purposes.
Fair values of Financial Instruments	Fair Values of Financial Instruments - The fair values of our derivative financial instruments were not significant at June 30, 2011. Our investments in cash equivalents, short-term investments and certain long-term investments are carried at fair value and are discussed in Note 6. The carrying values for other current financial assets and liabilities, such as accounts receivable and accounts payable, approximate fair value due to the short maturity of such instruments. The fair value of our long-term debt approximates the carrying value.

Valuation of debt and equity investments and certain liabilities [Abstract]
Investment policy	We classify our investments as available-for-sale, trading, equity method or cost method. Most of our investments are classified as available-for-sale. Available-for-sale and trading securities are stated at fair value, which is generally based on market prices, broker quotes or, when necessary, financial models (see fair value discussion below). Unrealized gains and losses on available-for-sale securities are recorded as an increase or decrease, net of taxes, in AOCI. We record other-than-temporary losses (impairments) on available-for-sale securities in OI&E. Changes in the fair value of debt securities classified as trading securities are recorded in OI&E. We classify certain mutual funds as trading securities. These mutual funds hold a variety of debt and equity investments intended to generate returns that offset changes in certain deferred compensation liabilities. We record changes in the fair value of these mutual funds and the related deferred compensation liabilities in selling, general and administrative expense. Our other investments are not measured at fair value but are accounted for using either the equity method or cost method. These investments consist of interests in venture capital funds and other non-marketable equity securities. Gains and losses from equity method investments are reflected in OI&E based on our ownership share of the investee’s financial results. Gains and losses on cost method investments are recorded in OI&E when realized or when an impairment of the investment’s value is warranted based on our assessment of the recoverability of each investment.

Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data. Our Level 2 assets consist of corporate obligations, some U.S. government agency securities and auction-rate securities that have been called for redemption. We utilize a third-party data service to provide Level 2 valuations, verifying these valuations for reasonableness relative to unadjusted quotes obtained from brokers or dealers based on observable prices for similar assets in active markets.</font></div><div style="line-height:120%;padding-left:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"></br></font></div><div style="line-height:120%;padding-left:25px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Level 3 - Uses inputs that are unobservable, supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models that utilize management estimates of market participant assumptions.</font></div><div style="line-height:120%;padding-left:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"></br></font></div><div style="line-height:120%;padding-left:25px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Our auction-rate securities are primarily classified as Level 3 assets. Auction-rate securities are debt instruments with variable interest rates that historically would periodically reset through an auction process. These auctions have not functioned since 2008. There is no active secondary market for these securities, although limited observable transactions do occasionally occur. As a result, we use a discounted cash flow (DCF) model to determine the estimated fair value of these investments as of each quarter end. The assumptions used in preparing the DCF model include estimates for the amount and timing of future interest and principal payments and the rate of return required by investors to own these securities in the current environment. In making these assumptions we consider relevant factors including: the formula for each security that defines the interest rate paid to investors in the event of a failed auction; forward projections of the interest rate benchmarks specified in such formulas; the likely timing of principal repayments; the probability of full repayment considering the guarantees by the U.S. Department of Education of the underlying student loans and additional credit enhancements provided through other means; and, publicly available pricing data for student loan asset-backed securities that are not subject to auctions. Our estimate of the rate of return required by investors to own these securities also considers the reduced liquidity for auction-rate securities. To date, we have collected all interest on all of our auction-rate securities when due and expect to continue to do so in the future. </font></div></div>

Contingencies [Abstract]
Warranty Costs and Product Liabilities Policy	We routinely sell products with an intellectual property indemnification included in the terms of sale. Historically, we have had only minimal, infrequent losses associated with these indemnities. Consequently, we cannot reasonably estimate or accrue for any future liabilities that may result. We accrue for known product-related claims if a loss is probable and can be reasonably estimated. During the periods presented, there have been no material accruals or payments regarding product warranty or product liability. Historically, we have experienced a low rate of payments on product claims. Although we cannot predict the likelihood or amount of any future claims, we do not believe they will have a material adverse effect on our financial condition, results of operations or liquidity. Consistent with general industry practice, we enter into formal contracts with certain customers that include negotiated warranty remedies. Typically, under these agreements, our warranty for semiconductor products includes: three years coverage; an obligation to repair, replace or refund; and a maximum payment obligation tied to the price paid for our products. In some cases, product claims may exceed the price of our products. From time to time, we also negotiate contingent consideration payment arrangements associated with certain acquisitions, which are recorded at fair value. We are subject to various legal and administrative proceedings. Although it is not possible to predict the outcome of these matters, we believe that the results of these proceedings will not have a material adverse effect on our financial condition, results of operations or liquidity.
