DESCRIPTION:
The IDT54/74FCT273T/AT/CT are octal D flip-flops built
using an advanced dual metal CMOS technology. The IDT54/
74FCT273T/AT/CT have eight edge-triggered D-type flip-
MR ^{flops with individual D inputs and O outputs. The common}
buffered Clock (CP) and Master Reset ( ) 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 corresponding flip-flop’s O
output.
MR ^{All outputs will be forced LOW independently of Clock or}
Data inputs by a LOW voltage level on the 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.
