MC54/74F109 DUAL JK POSITIVE EDGE-TRIGGERED FLIP-FLOP The MC54/74F109 consists of two high-speed, completely independent transition clocked JK flip-flops. The clocking operation is independent of rise and fall times of the clock waveform. The JK design allows operation as a D flip-flop (refer to F74 data sheet) by connecting the J and K inputs together.
