how to implement this?
Thanks in advance ..

 

Hi,
Welcome to AAC..
Please post your best attempt, we can then help.

Hello,

Did you already have a look at the 74163 datasheet?
That way you can see how the chip is working.

Welcome to AAC!

I got trouble using the 74163 IC and any necessary gates, design a 24-hours digital clock

Could you post the complete text for the problem? It's curious that you weren't allowed to use more appropriate counters.

 

@adamliu If you're serious about doing your assignment, don't wait until the last minute because the speed at which guidance will be offered will be limited by your efforts.

 

You should consider using a decade counter. It will make your life a great deal easier.

This is my best attempt.


Thanks in advance ...

 

It would be helpful if you told us what wasn't working.

You can't use RCO from the S1 counter to enable the S10 counter because RCO will never go HIGH.

74163 has synchronous clear, so you're decode logic is wrong.

Why are you connecting the outputs from the S1 counter to the S10 counter load inputs? You never load anything.

It appears that you've been working on this problem for 11 days. When is the assignment due? Why are you being asked to use binary counters instead of decade? Using decade for S1 would simplify the logic (slightly).

 

If you using old-fashioned TTL then use the divide-by-6 section of a 7492 for the tens, then a 74160 for the units.

 

I'll give you a hint. Since the clear function on 74163 counters is synchronous, you can't connect the clocks in parallel. Can you understand why?

If you'd post the complete text for the problem, as I asked you in your other thread, we might be able to understand why you're using binary counters instead of decade.
EDIT: Threads have just been combined.

Kudos to you for having a schematic that isn't unnecessarily difficult to read.
