Overview
The 74LV14DB,112 is a hex inverting Schmitt trigger integrated circuit produced by Nexperia USA Inc. This low-voltage Si-gate CMOS device is designed to provide six inverting buffers with Schmitt-trigger inputs, making it ideal for transforming slowly-changing input signals into sharply defined, jitter-free output signals. It is pin and function compatible with the 74HC14 and 74HCT14 series, offering a wide range of applications in noisy environments.
