Texas Instruments Inc. (TI) designs and makes semiconductors that the Company sells to electronics designers and manufacturers all over the world. The Company has four segments: Analog, Embedded Processing, Wireless and Other. The Company's products, more than 100,000 orderable parts, are integrated circuits that are used to accomplish many different things, such as converting and amplifying signals, interfacing with other devices, managing and distributing power, processing data, canceling noise and improving signal resolution. The Company sells catalog and, to a lesser extent, custom semiconductor products. The life cycles of catalog products generally span multiple years, with some products continuing to sell for decades after their initial release. The life cycles of custom products are generally determined by end-equipment upgrade cycles and can be as short as 12 to 24 months. In December 2013, TI acquired a building in the Chengdu Hi-Tech Zone from UTAC Chengdu Ltd.
