The SN74LVC125A features independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE) input is high. 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. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment.

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. The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed. The value of VCC is provided in the recommended operating conditions table. The package thermal impedance is calculated in accordance with JESD 51-7. For the D package: above 70°C, the value of Ptot derates linearly with 8 mW/K. For the PW package: above 60°C, the value of Ptot derates linearly with 5.5 mW/K.
