1. Contact local sales office for custom options.
2. XYY = assembly and date code.
3. Sample stock is generally held on part numbers listed in BOLD.
4. The leadless package family, which includes QFN, TQFN, DFN, TDFN and STDFN, has exposed copper (unplated) at the end of the
lead terminals due to the manufacturing process. A solder fillet at the exposed copper edge cannot be guaranteed and is not required
to ensure a proper bottom solder connection.
