JK flip-flop

A JK flip-flop is a digital memory device used in electronic systems to store a single bit of information. It has two inputs labeled J and K, and a clock input that triggers the device to change its state. When the clock signal activates the flip-flop, the outputs change based on the J and K inputs: setting or resetting the stored bit, or toggling it if both inputs are high. It functions as a fundamental building block for counting, data storage, and digital registers, enabling precise control of information flow within electronic circuits.
