NOTES:

1. See TB347 for details about reel specifications.

2. These 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). 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), see the ISL12022 device page. For more information about MSL, see TB363.
