FAST CMOS

OCTAL D FLIP-FLOP

WITH MASTER RESET

DESCRIPTION:

The FCT273T is an octal D flip-flop built using an advanced dual metal

CMOS technology. The FCT273T has eight edge-triggered D-type flip-

flops with individual D inputs and O 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 set-

up time before the low-to-high clock transition, is transferred to the corre-

sponding flip-flop’s O 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.
