MC74ACT640 Series Octal 3 State Inverting Transciever Surface Mount - SOIC-20
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.
