MICROCIRCUIT DATA SHEET
MN54AC273-X REV 1C1
Octal D Flip-Flop
General Description
The AC273 has eight edge-triggered D-type flip-flops with individual D inputs and Q
outputs. The common buffered Clock (CP) and Master Reset (MR) inputs 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-flops' 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.
