DM74ALS540A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

General Description
This octal buffer and line driver is designed to have the performance of the DM74ALS240A series and, at the same time, offer a pinout with inputs and outputs on opposite sides of the package. This arrangement greatly enhances printed circuit board layout. The 3-STATE control gate is a 2-input NOR such that if either G1 or G2 is HIGH, all eight outputs are in the high impedance state.

特性 Features

■ Advanced oxide-isolated, ion-implanted Schottky TTL
   process
■ Switching performance is guaranteed over full temperature
   and VCC supply range
■ Data flow-thru pinout (All inputs on opposite side from outputs)
■ P-N-P inputs reduce DC loading

简介

DM74ALS540A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DM74ALS540A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。
