description
The SN74AHCT14Q 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 (V_T+) and for negative-going (V_T−) signals.
