3 Description

The SNx4AHC14 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-Trigger action, the inverters have different input threshold levels for positive-going (V_T+) and negative-going (V_T–) signals.
