Overview
The SN74AHC14DRG4 is a hex Schmitt-Trigger inverter 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 resistant to noisy or slow inputs that could cause oscillation or excessive current draw. The device operates over a wide voltage range from 2V to 5.5V, making it versatile for various system applications.
