description
This single Schmitt-trigger inverter is designed for 1.65-V to 5.5-V VCC operation.
The SN74LVC1G14 device contains one inverter, and performs the Boolean function Y = A. The device
functions as an independent inverter, but because of Schmitt action, it may have dif ferent input threshold levels
for positive-going (V
The SN74LVC1G14 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.
