Overview
The SN74HCT14DTG4 is a hex Schmitt-Trigger inverter integrated circuit produced by Texas Instruments. This device contains six independent inverters, each performing the Boolean function Y = A in positive logic. The Schmitt-Trigger inputs are designed to provide a minimum separation between positive and negative switching thresholds, making them suitable for handling noisy or slow inputs without causing oscillation or excessive current draw.
