2. Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate

termination finish, which are 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 ICL3221, ICL3222, ICL3223, ICL3232, ICL3241,and ICL3243 device pages. For more
