74ACTQ273
Quiet Series Octal D-Type Flip-Flop
General Description
The ACTQ273 has eight edge-triggered D-type flip-flops
with individual D inputs and Q outputs. The common buff-
ered Clock (CP) and Master Reset (MR) input load and
reset (clear) all flip-flops simultaneously.
The register is fully edge-triggered. The state of each D-
type input, one setup time before the LOW-to-HIGH clock
transition, is transferred to the corresponding flip-flop’s Q
output.
All outputs will be forced LOW independently of Clock or
Data inputs by a LOW voltage level on the MR input. The
device is useful for applications where the true output only
is required and the Clock and Master Reset are common to
all storage elements.
The ACTQ utilizes Fairchild Quiet Series technology to
guarantee quiet output switching and improved dynamic
threshold performance. FACT Quiet Series features
GTO output control and undershoot corrector in addition
to a split ground bus for superior performance.
Features
s ICC 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 common clock and asynchronous master reset
s Outputs source/sink 24 mA
s 4 kV minimum ESD immunity

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 FACT circuits outside databook specifications.
