Overview
The 74LV14PW, produced by Nexperia (previously part of NXP Semiconductors), is a low-voltage Si-gate CMOS device that functions as a hex inverting Schmitt trigger. This integrated circuit provides six inverting buffers with Schmitt-trigger inputs, which are designed to transform slowly-changing input signals into sharply defined, jitter-free output signals. It is pin and function compatible with the 74HC14 and 74HCT14 models, making it versatile for various applications.
