description
This single 2-input positive-OR gate is designed for 1.65-V to 5.5-V VCC operation.
The SN74LVC1G32 performs the Boolean function
This device is fully specified for partial-power-down applications using I
preventing damaging current backflow through the device when it is powered down.
The SN74LVC1G32 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. The value of VCC is provided in the recommended operating conditions table.
3. The package thermal impedance is calculated in accordance with JESD 51.
