FACT DATA
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 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
• Outputs Source/Sink 24 mA
• ′ACT109 Has TTL Compatible Inputs
