74ACQ374 • 74ACTQ374
Quiet Series
 Octal D-Type Flip-Flop
with 3-STATE Outputs
General Description
The ACQ/ACTQ374 is a high-speed, low-power octal D-
type flip-flop featuring separate D-type inputs for each flip-
flop and 3-STATE outputs for bus-oriented applications. A
buffered Clock (CP) and Output Enable (OE) are common
to all flip-flops.
The ACQ/ACTQ374 utilizes FACT Quiet Series
 technol-
ogy to guarantee quiet output switching and improve
dynamic threshold performance. FACT Quiet Series fea-
tures GTO
 output control and undershoot corrector in
addition to a split ground bus for superior performance.
Features
s ICC and IOZ 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 Buffered positive edge-triggered clock
s 3-STATE outputs drive bus lines or buffer memory
address registers
s Outputs source/sink 24 mA
s Faster prop delays than the standard AC/ACT374
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
