Thanks.   The  findchips.com suggestion was good.  Seems the "74AC"
part really is not available but there is a "CD74ACxxx" part that
looks good.

The problem is, the PCB is already made so it is hard to adapt the
design to other parts.   If I were designing from scratch I'd only
select parts that were stocked in high volume by most distributers
