Step 1 of 1 7.08DP The operation of flip-flop and latch is same and the circuits are also almost similar but the only differnce is clock signal. Flipflops need clock signal but latch doesn't need it. Flip flop can be designed by using latch is giving a clock signal to the latch but latch cannot be created using flip-flop because a flip-flop need an external clock to operate where as latch require an enable which must be always at level '1'. Hence, one cannot drive a 74x74 dual edge triggered D flip-flop with the inputs of a latch. So designing a S- R latch using a single 74x74 positive edge triggered flip-flop is not possible.
