Quiet Series™ Octal D-Type Flip-Flop with 3-STATE
Outputs
Features
■ I_CC and I_OZ reduced by 50%
■ Guaranteed simultaneous switching noise level and
dynamic threshold performance
■ Guaranteed pin-to-pin skew AC performance
■ Improved latch-up immunity
■ Buffered positive edge-triggered clock
■ 3-STATE outputs drive bus lines or buffer memory
address registers
■ Outputs source/sink 24mA
■ Faster prop delays than the standard AC/ACT374
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 applica-
tions. A buffered Clock (CP) and Output Enable (OE) are
common to all flip-flops.
The ACQ/ACTQ374 utilizes FACT Quiet Series™ tech-
nology 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.
