MC74AC109, MC74ACT109
Dual JK Positive
Edge−Triggered Flip−Flop
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 S
D
makes both Q and Q HIGH
