74AC109 74ACT109
Dual JK Positive Edge-Triggered Flip-Flop
General Description
The AC/ACT109 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-Type
flip-flop (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 LOW level
Clear and Set are independent of clock
Simultaneous LOW on CD and SD makes
both Q and Q HIGH
Features
s ICC reduced by 50%
s Outputs source/sink 24 mA
s ACT109 has TTL-compatible inputs
