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 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
