FACT DATA
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 to CD (Clear) sets Q to LOW level
Clear and Set are independent of clock
Simultaneous LOW on CD and SD makes both Q and Q HIGH
Outputs Source/Sink 24 mA
ACT109 Has TTL Compatible Inputs
