74ACTQ74
Quiet Series Dual D-Type
Positive Edge-Triggered Flip-Flop
General Description
The 74ACTQ74 is a dual D-type flip-flop with Asynchro-
nous Clear and Set inputs and complementary (Q, Q) out-
puts. 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.
The ACTQ74 utilizes Fairchild Quiet Series technology to
guarantee quiet output switching and improved dynamic
threshold performance. FACT Quiet Seriesfeatures
GTOoutput control and undershoot corrector in addition
to a split ground bus for superior performance.
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
Features
s ICC reduced by 50%
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Guaranteed pin-to-pin skew AC performance
s Improved latch-up immunity
s 4 kV minimum ESD immunity
s TTL-compatible inputs
