Dual DType Positive
EdgeTriggered FlipFlop
The MC74AC74/74ACT74 is a dual D
type flip
flop with
Asynchronous Clear and Set inputs and complementary (Q,Q)
outputs. Information at the input is transferred to the outputs on the
positive edge of the clock pulse. Clock triggering occurs at a voltage
level of the clock pulse and is not directly related to the transition time
of the positive-going pulse. After the Clock Pulse input threshold
voltage has been passed, the Data input is locked out and information
present will not be transferred to the outputs until the next rising edge
of the Clock Pulse input.
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
