74F273

Octal D-Type Flip-Flop

General Description

Features

■ Ideal buffer for MOS microprocessor or memory

■ Eight edge-triggered D-type flip-flops

■ Buffered common clock

The 74F273 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.

■ Buffered, asynchronous Master Reset

■ See 74F377 for clock enable version

■ See 74F373 for transparent latch version

■ See 74F374 for 3-STATE version

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

input, one setup time before the LOW-to-HIGH clock transi-

tion, 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.
