description/ordering information
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 (V ) and negative-going (V ) signals.
