tm
Quiet Series™ Octal D-Type Flip-Flop with 3-STATE Outputs
Features
ICC and IOZ reduced by 50%
Guaranteed simultaneous switching noise level and
dynamic threshold performance
Guaranteed pin-to-pin skew AC performance
Inputs and outputs on opposite sides of the package
allowing easy interface with microprocessors
Functionally identical to the ACQ/ACTQ374
3-STATE outputs drive bus lines or buffer memory
address registers
Outputs source/sink 24mA
Faster prop delays than the standard AC/ACT574
General Description
The ACQ/ACTQ574 is a high-speed, low-power octal
D-type flip-flop with a buffered Common Clock (CP) and
a buffered common Output Enable (OE). The information
presented to the D inputs is stored in the flip-flops on the
LOW-to-HIGH clock (CP) transition.
ACQ/ACTQ574 utilizes FACT Quiet Series™ technology
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.
The ACQ/ACTQ574 is functionally identical to the
ACTQ374 but with different pin-out.
