MC74ACT640

Octal 3−State Inverting

Transciever

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.
