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
