Overview
The SN74HC14DTG4 is a hex inverter with Schmitt-Trigger inputs, manufactured by Texas Instruments. This device contains six independent inverters that perform 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.
