onsemi MC74AC109

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.
