74245 3-STATE Octal Bus Transceiver

These octal bus transceivers are designed for asynchronous two-way communication between data buses. The control function implementation minimizes external timing requirements. The device allows data transmission from the A Bus to the B Bus or from the B Bus to the A Bus depending upon the logic lev.
