NOTES:

1. Add “-T” suffix for 6k unit tape and reel. Refer to TB347 for details on reel specifications.

2. Add “-TK” suffix for 1k unit tape and reel. Refer to TB347 for details on reel specifications.

3. 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.
