54FCT377
Octal D-Type Flip-Flop with Clock Enable
General Description
The ’FCT377 has eight edge-triggered, D-type flip-flops with
individual D inputs and Q outputs. The common buffered
Clock (CP) input loads all flip-flops simultaneously, when the
Clock Enable (CE) is LOW.
The register is fully edge-triggered. The state of each D in-
put, one setup time before the LOW-to-HIGH clock transi-
tion, is transferred to the corresponding flip-flop’s Q output.
The CE input must be stable only one setup time prior to the
LOW-to-HIGH clock transition for predictable operation.
