description/ordering information
This single bus buffer gate is designed for 1.65-V to 5.5-V VCC operation.
The SN74LVC1G126 is a single line driver with a 3-state output. The output is disabled when the 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.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.

† Stresses beyond those listed under “absolute maximum ratings” may 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 conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed.
2. The value of VCC is provided in the recommended operating conditions table.
3. The package thermal impedance is calculated in accordance with JESD 51-7.
