DESCRIPTION:
The IDT54/74FCT273/A/C are octal D flip-flops built using
an advanced dual metal CMOS technology. The IDT54/
74FCT273/A/C have eight edge-triggered D-type flip-flops
MR 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.
All outputs will be forced LOW independently of Clock or
MR 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.
