Overview
The 74LVT14DB118 is a hex inverting Schmitt trigger integrated circuit produced by NXP USA Inc. This device is part of the 74LVT series, which is designed for low-voltage applications. It provides six inverting buffers with Schmitt-trigger inputs, enabling the transformation of slowly-changing input signals into sharply defined, jitter-free output signals. This component is pin and function compatible with other 74HC and 74HCT series devices, making it versatile for various design needs.
