SN74LS109A
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.
