Hi, I've been working on this circuit design for a while now, but I am having trouble getting the top 74163 chip used to count my tens place to work. I think my issue comes from me not knowing exactly where my P and T enablers are supposed to pull from. My bottom counter works counting from 0-9 and then resetting but, when I hit 9 nothing happens in my top counter. The counter is supposed to count from 00 to 59 and then rollover back to 00 while also having a dipswitch connected to manually hold the counter at 00. My current design is attached below:



Thank you!

Yes it is.

 

The information you need is in the datasheet.

Why are you using binary counters when decade would make implementing 0-59 easier?

Binary counters are required for this assignment.

OK. Have you read the datasheet to understand the function of P and T?

Are you required to clock the two counters synchronously?

 

Yes I am, once the bottom counter reaches 9 the top counter waits until the next clock to increment.
I believe I understand P and T.

 

You might not fully understand the meaning of binary counter.
Are you allowed to use a 74160 instead of 74163?

I am only allowed to use a 74163 to complete this assignment.

 

If you were asked to use flip-flops then that would be a reasonable request.
If you are allowed to use a 74163 ask your instructor why you are not allowed to use a 74160.

Perhaps if you posted the entire text of the problem we wouldn't have to play 20 questions.

Page 3 of the instructions doesn't require the 2 counters to be clocked synchronously.

EDIT:


EDIT2: The "helpful hints" section seems to imply that the two counters do have the same clock and that you're to use P and T to control when the 10's counter increments. It can be done either way, so you decide and we can provide tips if you can't figure out how to do it.
