A JK flip-flop is a clocked flip-flop
whose name comes from the two information inputs "J" and "K" and is probably due to the developer Jack Kilby. The JK flip-flop also has a clock input (C). The JK flip-flop operates in the same way as the RS flip-flop as long as different signals
K flip-flopThe JK flip-flop is also called master-slave flip-flop because it is composed of two flip-flops, a master and a slave
, which are controlled by the rising and falling edge of the clock pulse. JK flip-flops are used in shift registers and counters because all flip-flops of such a register can be set simultaneously.
