Overview
The SN74HCT14DBR is a hex Schmitt-Trigger inverter IC produced 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.
