So I have three CMOS EPROMs I need to place on a common bus, and I know that the usual way is to use a bus controller to switch the chips and avoid contention.
But in this case I would like to avoid using a controller, because I only need to switch the chips in sequence…123123123…etc.
So assuming the following…
The transition time between active and high Z is shorter or the same as high Z to active. (which it is with this chip, so that’s a plus to start)
Can I assume the following…
At each clock pulse to the counter, the active chip will enter high z state before the next becomes active due to the inherent nature of a ripple counter combined with the delay differences.
