Hi friends,
I have two 12-bit ripple counters cascaded together (74HC4040), and when they reach a certain 18bit value, I reset them by first setting a flip flop, and then at the next clock edge resetting the counter. This has worked for me before, but now it just isn't working! I have no idea why this could be.
The reset signal is 100ns, which is much more than the 45ns required.
Does anyone have any ideas or have gone through similar situations ?
