MC74AC273, MC74ACT273

Octal D Flip−Flop

The MC74AC273/74ACT273 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−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.
