Category: JK flip-flops 

A JK flip-flop is a versatile, edge-triggered storage element that extends the behavior of an SR flip-flop while eliminating its invalid input state. It has two inputs—J and K—and on each triggering clock edge it updates its output based on their combination: J=1 and K=0 sets the output, J=0 and K=1 resets it, J=0 and K=0 holds the current state, and J=1 and K=1 toggles the output. This predictable, flexible behavior makes the JK flip-flop useful in counters, frequency dividers, and general sequential logic where controlled state transitions are needed.
