description/ordering information

This device is designed to multiplex signals from 4-bit data sources to four output data lines in bus-organized

systems. The 3-state outputs do not load the data lines when the output-enable (OE) input is at a high logic level.

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

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