JK Flip Flop - Combination of SR and T Flip Flop
Instead of using a single control input T in T Flip Flop, two inputs J and K can be used instead such that D=JK'+J'K. This kind of flip flop is a beautiful combination of RS Flip Flop and T Flip Flop.
- Behaves as RS Latch / Flip Flop (here J=S and K=R) for all input values except for J=K=1
- For J=K=1, (this is state has to be avoided in SR), JK Flip Flop toggles the value similar to T-Flip Flop.
