IDT54/74FCT273T/AT/CT
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.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or
any other conditions above those indicated in the operational sections
of this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
No
terminal voltage may exceed Vcc by +0.5V unless otherwise noted.
2. Inputs and Vcc terminals only.
