What's On: Texas Instruments' CEO Talks National Semiconductor

Here's what's up on Tuesday's Squawk on the Street:

--The CEO of Texas Instruments will join us. The company made a major acquisition announcement, planning to buy National Semiconductor for $6.5 billion dollars. NatSemi is up big on the news, almost 70 percent Monday night.

--Also, Boeing's next move. If the company needs to replace aging airline fleets, what will it mean for the stock?

--KB Homes is out with numbers, and we'll have them along with instant market reaction as we count you down to the opening bell.

--The CEO of Aircastle is also on the big show.

--We're also following the possibility of a federal government shutdown very closely, the new budget deadline is Friday. As the clock ticks down to that possible shutdown, we want to know what you think about the impact of deeper budget cuts? Tell us if you think it'd be good for the US or if it could be a rally killer.

--Plus, we'll have a big debate on emissions. Can the United States afford to make a lot of changes right now? See who'll be happy about it and which stocks will take a hit.
