74AC74, 74ACT74
Dual D-Type Positive Edge-Triggered Flip-Flop
Features
■ ICC reduced by 50%
■ Output source/sink 24mA
■ ACT74 has TTL-compatible inputs
General Description
The AC/ACT74 is a dual D-type flip-flop with Asynchro-
nous Clear and Set inputs and complementary (Q, Q)
outputs. Information at the input is transferred to the out-
puts on the positive edge of the clock pulse. Clock trig-
gering 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 volt-
age 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 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
