Overview
The 74LVX14MX is a low-voltage hex inverter with Schmitt trigger inputs, produced by Fairchild Semiconductor (now part of onsemi). This component is designed to operate over a wide voltage range from 1.65V to 5.5V and is suitable for use in a broad temperature range of -55°C to +125°C. It features six inverter gates, each equipped with a Schmitt trigger input, which helps in transforming slowly changing input signals into sharply defined, jitter-free output signals. This makes the 74LVX14MX ideal for applications requiring low power and low noise, particularly in 3.3V systems.
