74ACT377PC集成电路（IC）的触发器规格书PDF中文资料

General Description

The AC/ACT377 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 input, one setup time before the LOW-to-HIGH clock transition, is transferred to the corresponding flip-flops Q output. The CE input must be stable only one setup time prior to the LOW-to-HIGH clock transition for predictable operation.
