74AC109 * 74ACT109 Dual JK Positive Edge-Triggered Flip-Flop
November 1988 Revised August 2000
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
