Hi Guys and Girls.

I am busy designing an Odd sequence 3 bit up down counter, I have got all my expressions and have started simulating on multisim but I am not sure how to connect my outputs of my JK flip flops (Q and Q-) to my decoder(74LS47N).

Any help or advice will be appreciated.

 

Hello Jade Rietmann

You analyzes the circuit contained in document .PDF attachment.

It was developed with the ISIS Proteus simulator.

I hope it helps you.

 

There are only 3 bits output from the JK namely Q0, Q1 and Q2. Connect Q0 to A and Q1 to B and Q2 to C inputs of 7447. Then just ground D inputs. The display would display 0 to 7 accordingly.

Is this a homework?

 

Thanks for the input.

This is for a project I have to build.
