54AC109
54ACT109
Dual JK Positive Edge-Triggered Flip-Flop
General Description
The ’AC/’ACT109 consists of two high-speed completely in-
dependent transition clocked JK flip-flops. The clocking op-
eration is independent of rise and fall times of the clock
waveform. The JK design allows operation as a D flip-flop
(refer to ’AC/’ACT74 data sheet) by connecting the J and K
inputs together.
Asynchronous Inputs:
LOW input to S
D (Set) sets Q to HIGH level
LOW input to C
D (Clear) sets Q to LOW level
Clear and Set are independent of clock
Simultaneous LOW on C
D and SD makes both Q and Q
HIGH
Features
n ICC reduced by 50%
n Outputs source/sink 24 mA
n ’ACT109 has TTL-compatible inputs
n Standard Military Drawing (SMD)
— ’AC109: 5962-89551
