General Description

This inverting octal bus transceiver is designed for asynchronous two-way communication between data busses. This device transmits data from the A bus to the B bus or from the B bus to the A bus depending upon the level at the direction control (DIR) input. The enable input (G) can be used to disable the device so the busses are effectively isolated.
