TI，英文全称为：Texas Instruments，中文名称为德州仪器。是全球领先的半导体公司，为现实世界的信号处理提供创新的数字信号处理(DSP)及模拟器件技术。除半导体业务外，还提供包括传感与控制、教育产品和数字光源处理解决方案。TI (Texas Instruments)总部位于美国得克萨斯州的达拉斯，并在25多个国家设有制造、设计或销售机构。

美国德州仪器TI (Texas Instruments)由塞瑟尔·H·格林、J·埃里克·约翰逊、尤金·麦克德莫特、帕特里克·E·哈格蒂在1947年创办。最初是其母公司地球物理业务公司（Geophysical Service Incorporated, GSI）用来生产新发明的晶体管的。

麦克德莫特是GSI最初在1930年创办时的创办者。麦克德莫特、格林、约翰逊后来在1941年买下了这个公司。

1945年11月，帕特里克·哈格蒂被雇佣为实验室和制造部门（Laboratory and Manufacturing (L&M)）部门的总经理。1951年L&M部门凭借其国防方面的合同，迅速超越了GSI的地理部门。公司被重新命名为“通用仪器”（General Instrument。同一年，公司又被再度命名为“德州仪器TI (Texas Instruments)”，也就是它如今的名字。GSI逐渐变成了德州仪器TI (Texas Instruments)的一个子公司，直到1988年GSI被出售给哈利伯托公司。

德州仪器TI (Texas Instruments)的半导体产品几乎占了其收入的85%（2003年数据）。在包括数字信号处理器、数字模拟转换器、模拟数字转换器、能源管理、模拟集成电路等不同产品领域都占据领先位置。无线通信也是德州仪器的一个焦点，全球有大约50%的移动电话都装有德州仪器TI (Texas Instruments)生产的芯片。同时它也生产针对应用的集成电路以及单片机等。

德州仪器 TI (Texas Instruments) 是全球领先的数字信号处理与模拟技术半导体供应商，亦是推动因特网时代不断发展的半导体引擎。

----作为实时技术的领导者，TI (Texas Instruments)正在快速发展，在无线与宽带接入等大型市场及数码相机和数字音频等新兴市场方面，TI (Texas Instruments)凭借性能卓越的半导体解决方案不断推动着因特网时代前进的步伐！

----TI (Texas Instruments)预想未来世界的方方面面都渗透着 TI (Texas Instruments) 产品的点点滴滴，您的每个电话、每次上网、拍的每张照片、听的每首歌都来自 TI数字信号处理器(DSP) 及模拟技术的神奇力量。

2011年4月5日，德州仪器TI (Texas Instruments)和美国国家半导体（NS）宣布签署合并协议，TI (Texas Instruments)将以25美元/股、总额约65亿美元的现金价格，收购国家半导体。本次收购将使业界共同致力于解决客户模拟问题的两个领导者实现强强联手。

德州仪器TI (Texas Instruments)也是图形计算器的重要生产商，其生产的TI 图形计算器系列享誉全球。

TI (Texas Instruments)公司设计和制造模拟技术、数字信号处理 (DSP)和微控制器(MCU)半导体。TI (Texas Instruments)是模拟和数字嵌入式及应用处理半导体解决方案的领导者。作为一家全球半导体公司，TI (Texas Instruments)在30多个国家通过设计、销售和制造领域的运营，开展创新。工程开发工具帮助设计工程师评估、创建或调试基于半导体设备的设计。 开发工有多种形式，包括启动装置套件、评估板、调试程序或全套的开发环境在 TI (Texas Instruments) 发展之初，公司的目标是利用公司独有的技术能力从根本上颠覆传统市场，创造全新的市场。TI (Texas Instruments)的发展历程中始终贯穿一条清晰的主线，就是运用越来越先进的实时信号处理技术，实现从量变到质变的进步，真真切切地不断改变世界。

Texas Instruments Inc. (TI) is an American technology company that designs and manufactures semiconductors, which it sells to electronics designers and manufacturers globally. Headquartered in Dallas, Texas, United States, TI is one of the top ten semiconductor companies worldwide, based on sales volume. Texas Instruments's focus is on developing analog chips and embedded processors, which accounts for more than 85% of their revenue. TI also produces TI digital light processing (DLP) technology and education technology products including calculators, microcontrollers and multi-core processors. To date, TI has more than 43,000 patents worldwide.

Texas Instruments emerged in 1951 after a reorganization of Geophysical Service Incorporated, a company founded in 1930 that manufactured equipment for use in the seismic industry, as well as defense electronics. TI produced the world's first commercial silicon transistor in 1950, and designed and manufactured the first transistor radio in 1954. Jack Kilby invented the integrated circuit in 1958 while working at TI's Central Research Labs. TI also invented the hand-held calculator in 1967, and introduced the first single-chip microcontroller (MCU) in 1970, which combined all the elements of computing onto one piece of silicon.

In 1987, TI invented the digital light processing device (also known as the DLP chip), which serves as the foundation for the company's award-winning DLP technology and DLP Cinema. In 1990, TI came out with the popular TI-81 calculator which made them a leader in the graphing calculator industry. In 1997, its defense business was sold to Raytheon, which allowed TI to strengthen its focus on digital solutions. After the acquisition of National Semiconductor in 2011, the company had a combined portfolio of nearly 45,000 analog products and customer design tools, making it the world's largest maker of analog technology components.

Texas Instruments was founded by Cecil H. Green, J. Erik Jonsson, Eugene McDermott, and Patrick E. Haggerty in 1951. McDermott was one of the original founders of Geophysical Service Inc. (GSI) in 1930. McDermott, Green, and Jonsson were GSI employees who purchased the company in 1941. In November, 1945, Patrick Haggerty was hired as general manager of the Laboratory and Manufacturing (L&M) division, which focused on electronic equipment. By 1951, the L&M division, with its defense contracts, was growing faster than GSI's Geophysical division. The company was reorganized and initially renamed General Instruments Inc. Because there already existed a firm named General Instrument, the company was renamed Texas Instruments that same year. From 1956 to 1961, Fred Agnich of Dallas, later a Republican member of the Texas House of Representatives, was the Texas Instruments president. Geophysical Service, Inc. became a subsidiary of Texas Instruments. Early in 1988 most of GSI was sold to the Halliburton Company.
