Task $3$: Bidirectional register

Use four $74$LS$74$ D$-$flip$-$flops to create a bidirectional register which can store four bits. How do the

flip$-$flops need to be connected? Please note that you now need an extra input to determine whether

the data are shifted left or right. Make sure you don't leave the preset and clear unconnected.

For this task you need to:

Construct a bidirectional register which can store four bits using $74$LS$74$ D$-$flip$-$flops

Label your inputs clearly.

Use switches for the inputs and digital probes for the outputs to demonstrate that that the register

works

Make screenshots of the circuit during simulation
