Driving demand was TI's analog business, as well as increased demand for its calculators. But earnings were up across all of TI's business segments, and the company said that demand had risen particularly for chips used in mobile devices in China.

TI's operating profit fell $490 million, compared with the year-ago quarter, due partly to lower sales, but also because of costs involved with restructuring as well as underused assets. However, operating profit was up by $333 million over the first quarter. Excluding restructuring charges of $85 million,TI's operating profit was $428 million.

Drilling down into its main businesses, TI's analog segment -- especially for its high-performance analog and power-management products, showed strength over the previous quarter. In its Embedded Processing business, the company saw a decline in automotive products but an increase in demand for communications-infrastructure products.

The big driver, though, was increased sales from the prior quarter due to higher catalog-product revenue. In its wireless business, revenue fell from a year ago due to lower baseband sales, but revenue increased for its connectivity products. Finally, the company saw a decline in revenue from royalties, from its DLP line of products and ASIC processors, from year ago.

The company did repurchase stock during the quarter. TI used $251 million in the quarter to repurchase 13.4 million shares, and it paid dividends of $139 million.

Looking forward, the company said to expect revenue of $2.5 to $2.8 billion and earnings per share of 29 cents to 39 cents per share in its third quarter.
