description/ordering information

The SN74AHC1G126 is a single bus buffer gate/line driver with 3-state output. The output is disabled when the

output-enable (OE) input is low. When OE is high, true data is passed from the A input to the Y output.

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.
