I'm trying to create a
Program Counter using some JK flip-flops.
I have two different way to do that:
74LS73(dual JK flip-flop with clear):
74LS10(triple input NAND) and
74LS00(double input NAND):
Using the first integrated circuit will be easier, but this isn't the problem.
My doubt is about the Clear pin in
74LS73: I know it will reset the flip-flop but also the combination J=0 and K=1 on a rising clock edge should do it...
So, what is the difference between the Clear pin and J=0, K=1, rising clock?
