The is an octal Bus Transceiver with 3-state outputs. It is designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements. When the OE\ is low, the device passes non-inverted data from the A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the direction-control DIR input. A high on OE\ disables the device so that the buses are effectively isolated. To ensure the high-impedance state during power up or power down, OE\ should be tied to VCC through a pull-up resistor, the minimum value of the resistor is determined by the current-sinking capability of the driver.
