description
This quadruple bus buffer gate is designed for 1.65-V to 3.6-V VCC operation.
The SN74ALVC125 features independent line drivers with 3-state outputs. Each output is disabled when the
associated output-enable (OE
T o ensure the high-impedance state during power up or power down, OE
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN74ALVC125 is characterized for operation from –40°C to 85°C.

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 negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. This value is limited to 4.6 V maximum.
3. The package thermal impedance is calculated in accordance with JESD 51.
