description

The ’AHC14 devices contain six independent
inverters. These devices perform 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.
