Description

General part information

SN74AHCT14Q-Q1 Series

The SN74AHCT14 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 (VT+) and for negative-going (VT–) signals.

The SN74AHCT14 contains six independent inverters. This device performs the Boolean function Y = A\.
