com SN74LS109A Dual JK Positive Edge-Triggered Flip-Flop The SN74LS109A 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 by simply connecting the J and K pins together.
