74AC273 • 74ACT273

Octal D-Type Flip-Flop

General Description

Features

■ Ideal buffer for microprocessor or memory

■ Eight edge-triggered D-type flip-flops

■ Buffered common clock

The AC273 and ACT273 have eight edge-triggered D-type

flip-flops with individual D-type inputs and Q outputs. The

common buffered Clock (CP) and Master Reset (MR) input

load and reset (clear) all flip-flops simultaneously.

■ Buffered, asynchronous master reset

■ See 377 for clock enable version

■ See 373 for transparent latch version

■ See 374 for 3-STATE version

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.

■ Outputs source/sink 24 mA

■ 74ACT273 has TTL-compatible inputs
