Octal D Flip-Flop with Clock Enable
General Description
The ’F377 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 tran-
sition, is transferred to the corresponding flip-flop’s Q out-
put. The CE input must be stable only one setup time prior
to the LOW-to-HIGH clock transition for predictable opera-
tion.
