Part Numbering - Texas Instrument - General


#1

What does the suffix WAD and WAH call out and what are the differences in Texas Instrument parts?


#2

The “WAD” suffix was originally the RoHS version of this device, and the “WAH” device was the standard lead containing part number. The “WAD” has a RoHS Conversion date of Aug. 2005. The “WAH” became RoHS on Dec. 2005. Both the WAH and WAD are DIP Module, ECP packages. Functionally, they are the same.
