The MC74ACT640 octal bus transceiver is designed for asynchronous two-way communication between data buses. The device transmits data from bus A to bus B when T/R = HIGH, or from bus B to bus A when T/R = LOW. The enable input can be used to disable the device so the buses are effectively isolated.

Features

• Bidirectional Data Path

• A and B Outputs Sink 24 mA/Source −24 mA

• TTL Compatible Inputs

• Pb−Free Packages are Available*

MC74ACT640DW属于集成电路（IC） > 缓冲器，驱动器，接收器，收发器。安森美半导体公司制造生产的MC74ACT640DW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。
