Overview
The SN74HCT14DE4 is a hex Schmitt-trigger inverter integrated circuit manufactured 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 that could cause issues with standard CMOS inputs.
