- I already have a prototype made of 4 independant 16 bit counters, and
- working with 4 bit counters (74F161) are a pain.

- What I really would like is 4 addressable independant 16 bit counters
- running off a single clock (no load register needed) with a common

- I guess it's one of those things that falls through the cracks. It's
- too big and too specialized for a 74xx series part. A PLD may be
- expensive or slow or consume too much power. A low end gate array might
- be over-kill. Oh, well. In a production setting, even a handful of
- 74xx series glue chips can be fairly closely packed, using surface mount
- parts and using both sides of the board. Directly bonding the die onto
- the PC board is also becoming more popular.
