description/ordering information
These octal bus transceivers are designed for asynchronous communication between data buses. The devices
transmit data from the A bus to the B bus or from the B bus to the A bus, depending on the logic 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.
