MC74LCX240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 MC74LCX240 is a high performance, inverting octal buffer operating from a 2.3 to 3.6V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5V allows MC74LCX240 inputs to be safely driven from 5V devices. The MC74LCX240 is suitable for memory address driving and all TTL level bus oriented transceiver applications.Current drive capability is 24mA at the outputs. The Output Enable(OEbar) input, when HIGH, disables the outputs by placing them in a HIGH Z condition.

简介

MC74LCX240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MC74LCX240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。
