DUAL JK POSITIVE

EDGE-TRIGGERED

FLIP-FLOP

The MC74AC109/74ACT109 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

MC74AC74/74ACT74 data sheet) by connecting the J and K inputs together.

Asynchronous Inputs:

LOW input to S (Set) sets Q to HIGH level

LOW input to C (Clear) sets Q to LOW level

Clear and Set are independent of clock

Simultaneous LOW on C and S makes both Q and Q HIGH
