National Semiconductor (often briefly referred to as National ') was a manufacturer of integrated circuits. The company had its headquarters in Santa Clara (California / USA). In autumn 2011 it was acquired by Texas Instruments.


National was founded on 27 May 1959 a number of engineers who came from the Sperry Rand Corporation, in Danbury (Connecticut / USA). 1967 moved to the headquarters in Santa Clara, California. Over the years, National bought several other companies, such as Fairchild Semiconductor in 1987 and Cyrix in 1997. Since, however, more and more hosted on analog technology, these companies were spun off with time. After Fairchild Semiconductor in 1997 was made again into a separate company, they sold the Cyrix Microprocessors Division in 1999 to the Taiwanese company VIA Technologies. Followed in 2002 by the sale of the Information Appliance Division of National AMD. Other operations primarily digital in nature, for example wireless chipsets, image sensors and I / O chipsets for PCs, have either been discontinued or sold. The original idea was to position itself as a destination in mind, as a national provider of analog semiconductor devices. On September 23, 2011 National was acquired by Texas Instruments for $ 6.5 billion.


The product portfolio of National Semiconductor included before the acquisition by TI among others products related to power management, audio and operational amplifiers, communication interface products, sensors and data converters. These products are now integrated into the product range of TI, National Semiconductor is the name disappears product updates.

Before focusing on analog semiconductors National also had digital components such as logic blocks, memory and microprocessors ( NS320xx, SC / MP, Geode ) in the program.


Manufacturing facilities of National were last in South Portland (USA), in Greenock (Scotland) and Malacca (Malaysia), others in Arlington ( USA) and Suzhou (China) had already been closed in 2009. About half of the 18 development centers were located in the United States, the rest in Europe and Asia. The European headquarters of the company was based in Germany ( Fürstenfeldbruck).
