MC74ACT109 - Dual JK Positive Edge Triggered Flip-Flop
MC74AC109, MC74ACT109 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 SD (Set) sets Q to HIGH level LOW input
