Hello, I'm trying to experiment with
'163 counters.
I just want to cascade three of them. Or perhaps more but I'd like to understand how to cascade more than two basically.
I already have two perfectly cascaded:
- they share the CLK line
- ENP of counter 2 is connected to RCO of counter 1
The problem is how to cascade the third one: if I share clock and make its ENP connect to RCO of counter 2, that makes it count exactly like counter 1 when counter 2 is in HHHH state.
I really would like to understand what is the "correct" way to cascade more than two counters. I thought about ANDing the two RCO outputs and make those the ENP of counter 3 but it seems like a waste, having to use an extra logic gate/IC (and also: I have to mind about the delay? That won't matter when I count at 1Hz but I plan to take the counters up to 10MHz).
Is there a general way to proceed? IE: what if I want to cascade 10 or 20 counters?
Cheers
