NOTES:
1. Refer to TB347 for details about reel specifications.
2. These plastic packaged products are RoHS compliant by EU exemption 7C-I and employ special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3) termination finish which is compatible with both SnPb and Pb-free soldering operations. RoHS
compliant 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 ISL8200AM product information page. For more information about MSL, see TB363.
