FK PACKAGE (TOP VIEW) GND NC – No internal connection 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 (VT+) and negative-going (VT–) signals.
