Hi. Does anybody know of a counter circuit, or even better, a counter chip. What I mean is, a circuit that counts up according to clock input signals, ie, when 2 clock inputs are fed in, it lights 2 LEDs, OR better, displays 2 on a 7 segment. I can make one using 4 NAND gates and a dual JK flip flop, but that will only count up to four. I am ideally looking at one which will go up to 100, or possibly more. As you can imagine, 100 quad NAND and another 100 flip flops would be crazy. Also, the circuit needs to be able to deal with very fast clock signals (100khz+), but I doubt that will be a problem.
