Texas Instruments Inc posted lower profit and revenue as its customers are "increasingly cautious in placing new orders" because of global economic uncertainties.

The maker of chips used in a wide range of products such as cellphones and industrial equipment reported earnings of $446 million, or 38 cents per share, compared with $672 million, or 56 cents per share, in the year-ago quarter.

Revenue fell to $3.34 billion from $3.46 billion and compared with analysts' average expectation for $3.35 billion according to Thomson Reuters I/B/E/S.

The results were reported after regular stock-market trading ended Monday.
