74ALVCH245WM中文资料Low Voltage Bidirectional Transceiver with Bushold数据手册ONSEMI规格书

描述 Description

General Description
The ALVCH245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The T/R input determines the direction of data flow. The OE input disables both the A and B Ports by placing them in a high impedance state. The ALVCH245 data inputs include active bushold circuitry, eliminating the need for external pull-up resistors to hold unused or floating data inputs at a valid logic level.

简介

74ALVCH245WM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74ALVCH245WM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。
