description
The SN74AHC1G14 contains one inverter gate. The device performs the Boolean function Y = A.
The device functions as an independent inverter gate, but because of the Schmitt action, gates may have
different input threshold levels for positive- (VT+) and negative-going (VT–) signals.
The SN74AHC1G14 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 and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51.
