Quiet SeriesOctal D-Type Flip-Flop
with 3-STATE Outputs
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 Seriestechnology to
guarantee quiet output switching and improve dynamic
threshold performance. FACT Quiet Series features 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.
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 Inputs and outputs on opposite sides of the package
allowing easy interface with microprocessors
s Functionally identical to the ACQ/ACTQ374
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/ACT574

Functional Description
The ACQ/ACTQ574 consists of eight edge-triggered flip-
flops with individual D-type inputs and 3-STATE true out-
puts. The buffered clock and buffered Output Enable are
common to all flip-flops. The eight flip-flops will store the
state of their individual D-type inputs that meet the setup
and hold time requirements on the LOW-to-HIGH Clock
(CP) transition. With the Output Enable (OE) LOW, the
contents of the eight flip-flops are available at the outputs.
When OE is HIGH, the outputs go to the high impedance
state. Operation of the OE input does not affect the state of
the flip-flops.

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, with-
out exception, to ensure that the system design is reliable over its power
supply, temperature, and output/input loading variables. Fairchild does not
recommend operation of FACTcircuits outside databook specifications.
