74AC377 鈥?74ACT377 Octal D-Type Flip-Flop with Clock Enable
November 1988
Revised November 1999
74AC377 鈥?74ACT377
Octal D-Type Flip-Flop with Clock Enable
General Description
The AC/ACT377 has eight edge-triggered, D-type flip-flops
with individual D inputs and Q outputs. The common buff-
ered 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
input, one setup time before the LOW-to-HIGH clock transi-
tion, is transferred to the corresponding flip-flop鈥檚 Q output.
The CE input must be stable only one setup time prior to
the LOW-to-HIGH clock transition for predictable operation.
