MC74AC540数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

The MC74AC540/74ACT540 and MC74AC541/74ACT541 are octal buffer/linedrivers designed to be employed as memory and address drivers, clock drivers andbus oriented transmitter/receivers. The MC74AC541/74ACT541 is a noninvertingoption of the MC74AC540/74ACT540. These devices are similar in function to the MC74AC240/74ACT240 andMC74AC244/74ACT244 while providing flow-through architecture (inputs on oppositeside from outputs). This pinout arrangement makes these devices especially usefulas output ports for microprocessors, allowing ease of layout and greater PC boarddensity.

简介

MC74AC540属于集成电路（IC）的缓冲器驱动器接收器收发器。由制造生产的MC74AC540缓冲器，驱动器，接收器，收发器逻辑缓冲器、驱动器、接收器和收发器允许隔离对某个电路的逻辑信号的访问，以用于另一电路。缓冲器将其输入信号（不变或反相）传递到其输出，并可能用于清除弱信号或驱动负载。在布尔逻辑仿真器中，缓冲器主要用于增加传播延迟。逻辑接收器和收发器允许在数据总线之间进行隔离通信。
