description
The SN74AHC14Q contains six independent inverters. This device performs the Boolean function Y = A.
Each circuit functions as an independent inverter, but because of the Schmitt action, the inverters have different
input threshold levels for positive-going (VT+) and negative-going (VT−) signals.

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 51-7.
