*Add “-T” suffix to part number for tape and reel packaging.
NOTE:
2. Intersil Pb-free products employ special Pb-free material sets; molding compounds/die
attach materials and 100% matte tin plate termination finish, which is 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-020B.
