MC74ACT109N Datasheet PDF - ON Semiconductor

●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
