Selection Guide

1Pb-based variants are being phased out of the product line. The variants cited in this footnote are in production but have

been determined to be NOT FOR NEW DESIGN. This classiﬁcation indicates that sale of this device is currently restricted to

existing customer applications. The variants should not be purchased for new design applications because obsolescence in the

near future is probable. Samples are no longer available. Status change: May 1, 2006. These variants include: A3422EKA and

A3422LKA.
