NOTES:

1. Add “-T” suffix for 6k unit or “-TK” suffix for 1k unit tape

and reel options. 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.

3. For Moisture Sensitivity Level (MSL), please see device

information page for ISL97672. For more information on

MSL please see techbrief TB363.
