54AC109 Datasheet - National Semiconductor

54AC109 Dual JK Positive Edge-Triggered Flip-Flop

The ’AC/’ACT109 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 ’AC/’ACT74 data sheet) by connecting the J and K inputs to.
