Yes, someone else has told me this via e-mail, and I will respond to that, and others have informed me on other 74x replacements. >Why is it important to get an 8 bit counter in one package, as >opposed to tying two 4-bit counters together ? 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...
