PRODUCT IDENTIFICATION SYSTEM

To order or obtain information, e.g., on pricing or delivery, refer to the factory or the listed sales office

.

Note:

Most products manufactured after January 2005 will have a Matte Tin (Pb-free) finish. Most products manufactured

before January 2005 will have a finish of approximately 63% Sn and 37% Pb (Sn/Pb).

Please visit www.microchip.com/Pbfree for the latest information on Pb-free conversion, including conversion date codes.
