description/ordering information
These octal bus transceivers are designed for asynchronous two-way communication between data buses.
These devices transmit 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 output-enable (OE) input can be used to disable the device so the
buses are effectively isolated.
