description/ordering information (continued)

The SN74LVC2G126 is a dual bus driver/line driver with 3-state outputs. The outputs are 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

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

driver.

preventing damaging current backflow through the device when it is powered down.
