description/ordering information

These quadruple bus buffer gates feature independent line drivers with 3-state outputs. Each output is disabled

when the associated output-enable (OE) input is low.

To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pullup

resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.
