-
- 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
- clear but with individual 'counter-freeze' lines. There would be an
- internal latch to hold each counters value (when the freeze line was
- activated) and a single tri-state buffer for the output.
-
- I'll put that on my Chistmas wish list...
