I was studying for exams and i came across this problem. It said to use a 7493 counter and as low as possible gates to construct a 160:1 divider
I would appreciate it if anyone could provide a picture with the appropriate connections.

If the counter can have 16 states, then how many will it take to divide by 160?

Why not get a data sheet and make a stab at connecting multiple '93's?

160 in binary system is 10100000 so you need two 7493
counter and one AND gate that's detect the "1" and reset the counters.
Ups my mistake, of course you need to detect 161d = 10100001.
So you need to detect a "three-1" with 3-input AND gate.

Can you define what exactly do you mean with a 'three-1' detection? I couldn't get that part...

If the count began at 1, you'd be correct.
However, it starts at 0.
So, the counters need to be reset when the output is 10100000, or 160d.
