description/ordering information
These devices are designed to multiplex signals from 4-bit data sources to 4-output data lines in bus-organized
systems. The 3-state outputs do not load the data lines when the output-enable (G) input is at a high logic level.
To ensure the high-impedance state during power up or power down, G 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.

Stresses beyond those listed under absolute maximum ratingsmay cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditionsis not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51-7.
