OCTAL BIDIRECTIONAL  
TRANSCEIVER WITH  
3-STATE OUTPUTS  
The MC74AC640/74ACT640 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.
