54AC109

Dual JK Positive EdgeTriggered FlipFlop
General Description
The ’AC/’ACT109 consists of two highspeed completely in dependent transition clocked JK flipflops. The clocking operation is independent of rise and fall times of the clock waveform. The JK design allows operation as a D flipflop (refer to ’AC/’ACT74 data sheet) by connecting the J and K inputs together.
Asynchronous Inputs:
LOW input to SD (Set) sets Q to HIGH level
LOW input to CD (Clear) sets Q to
