Question

19. Why are JK flip-flops often preferred to SR flip-flops?

TextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbook

Answer

JK flipflops are often preferred to SR flipflops because,

  • The J-K flip-flop is much faster. The J-K flip-flop does not have propagation delay problems. The J-K flip-flop has a toggle state.
  • The advantage of a JK flip-flop is that it removes the not allowed condition present in the SR flip-flop for an input of SR=11. ... It has two NAND gates and the input of both the gates is connected to different outputs.
