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.
