Notes:
1. See test circuit and wave forms.
2. This parameter is guaranteed but not production tested.
3. “Not valid” means the setup time indicated is not sufficient to assure proper functioning of this output; however,
the set-up time indicated will assure proper functioning of the A-to-B or B-to-A port respective to the indicated
direction.
