Your help please!
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
Could anyone please help??
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...

 

Look at schematics.
Schematics show a mod-50 counter.
50=110010b And look how the AND gate detect a "1" to reset the counter.
U1-->Qb=2^1=2d
U3-->QA=2^4=16d
U3-->QB=2^5=32d
So AND gate will reset counter at 2+16+32=50

thank you all for your answers. I think i 've found the solution.

I like your drawing how do you do it. Is it with the help of some s/w if it is pl let me know some free s/w to try it.
Thanks.

 

The schematic was draw in multisim.
And can you explain the meaning of "s/w"

 

I mean to say software
what is multisim ? how can i get it is it free on the net?

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.

Yes you can:
