What's the difference between '163 and '193?
'163- can only count up and stops at the number you want
'193- can count up OR down and count +1
Describe the process you went through to build your circuit.
For the MultiSim design, I used 2 different circuits: MSI and SSI. It's basically the same as the deli counter but instead of used 4 JK flip-flops, I used three because the SSI counter only has to count up to 6 and six in binary is 110 so you only need 3 flip-flops to show 6. The only thing I changed on the MSI counter is that instead of using a 74LS93N chip, I used a 74LS163 chip. Since the MSI logic had to count from 0-9, I connected the A, B, C, and D inputs to ground because ground is 0 and you want to start at 0. I connected the next 2 inputs to power and then I connected LOAD to the output of a 4-input NAND gate and I connected CLEAR to the switch because it'll clear the HEX Display when I toggle it. I also connected the clock to the clock. After that, I added a '48 chip and connected the outputs of the '163 A, B, C, and D to the '48 A, B, C, and D inputs. Then I connected the other 3 inputs to power.
Did any of your classmates create a circuit design different from yours? How was it different?
Yes, since everyones 60 second counter is based on their deli counter, everyones is different whether it be by the type of flip flop or the different types of gates used.
