NEW YORK, Oct 20 - Chip maker Texas Instruments Inc warned that its fourth-quarter results would fall far short of expectations, sending its shares down 5 per cent, in the latest sign that the economic crisis is hurting demand for everything from cell phones to industrial equipment.

TI, which has been losing customers to wireless rivals such as Qualcomm Inc and ST Microelectronics, also announced a plan to sell part of a unit that makes wireless baseband chips, which are the brains of mobile phones.
