*Variant is in production but has been determined to be NOT FOR NEW DESIGN. This classifi-
cation indicates that sale of the variant is currently restricted to existing customer applications.
The variant should not be purchased for new design applications because obsolescence in the
near future is probable. Samples are no longer available. Status change: May 4, 2009.
