NOTES:

1. Add “-T*” suffix for tape and reel.

Please refer to TB347 for details

on reel specifications.

2. These Intersil Pb-free plastic packaged products employ special Pb-

free material sets, molding compounds/die attach materials, and

100% matte tin plate plus anneal (e3 termination finish, which is

RoHS compliant and compatible with both SnPb and Pb-free

soldering operations). Intersil Pb-free products are MSL classified at

Pb-free peak reflow temperatures that meet or exceed the Pb-free

requirements of IPC/JEDEC J STD-020.
