MC74AC377数据手册集成电路（IC）的触发器规格书PDF

描述 Description

The MC74AC377/74ACT377 has eight edge-triggered, D-type flip-flops withindividual D inputs and Q outputs. The common buffered Clock (CP) input loadsall flip-flops simultaneously, when the Clock Enable (CE) is LOW. The register is fully edge-triggered. The state of each D input, one setup timebefore the LOW-to-HIGH clock transition, is transferred to the corresponding flipflop's Q output. The CE input must be stable only one setup time prior to theLOW-to-HIGH clock transition for predictable operation.

简介

MC74AC377属于集成电路（IC）的触发器。由制造生产的MC74AC377触发器触发器是能够存储单个逻辑状态或信息“位”的基本数字存储器件。这些器件至少有两个输入；一个或多个用于传递要存储的数据，另一个用于指示存储该数据的时间点。不同的触发器类型，例如 D（延迟）、SR（置位复位）和 JK，对提供给其输入的信号有不同的响应，可用于实现不同的逻辑功能。这些器件与锁存器的不同之处在于它们是边缘敏感器件，其保持的逻辑状态仅在接收到有效时钟信号时才会改变。
