MN54ACTQ273-X REV 2A0 MICROCIRCUIT DATA SHEET
Octal D-Type Flip-Flop With Master Reset
General Description
The ACTQ273 has eight edge-triggered D-type flip-flops with individual D inputs and Q
outputs. The common buffered 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 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 NSC Quiet Series technology to guarantee quiet output switching and
improve dynamic threshold performance. FACT Quiet Series TM features GTO TM output
control and undershoot corrector in addition to a split group bus for superior
performance.

Note 1: Absolute maximum ratings are those values beyond which damage to the device may
occur. The databook specifications should be met, without exception, to ensure that
the system design is reliable over its power supply, temperature, and output/input
loading variables. National does not recommend operation of FACT TM circuits outside
databook specifications.
