J-K Flip-Flop with Asynchronous Clear

FJKC is a single J-K-type flip-flop with J, K, and asynchronous clear (CLR) inputs and data output (Q). The asynchronous clear (CLR) input, when High, overrides all other inputs and resets the Q output Low. When CLR is Low, the output responds to the state of the J and K inputs, as shown in the following truth table, during the Low-to- High clock (C) transition. The default initial state of the flip-flop is zero.
