54AC/74AC273

Octal D Flip-Flop

General Description

Features

Ideal buffer for microprocessor or memory

The ’273 has eight edge-triggered D-type flip-flops with indi-

vidual D inputs and Q outputs. The common buffered Clock

(CP) and Master Reset (MR) input load and reset (clear) all

flip-flops simultaneously.

Eight edge-triggered D flip-flops

Buffered common clock

Buffered, asynchronous master reset

The register is fully edge-triggered. The state of each D in-

put, one setup time before the LOW-to-HIGH clock tran-

sition, is transferred to the corresponding flip-flop’s Q out-

put.

See ’377 for clock enable version

See ’373 for transparent latch version

See ’374 for TRI-STATE version

Outputs source/sink 24 mA

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.
