Quiet Series™ Octal D-Type Flip-Flop with 3-STATE
tm
Outputs
Features
ICC and IOZ 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.

Notes:
10. Voltage range 5.0 is 5.0V ± 0.5V. Voltage range 3.3 is 3.3V ± 0.3V.
11. Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate
outputs of the same device. The specification applies to any outputs switching in the same direction, either
HIGH-to-LOW (tOSHL) or LOW-to-HIGH (tOSLH). Parameter guaranteed by design.
