Overview
The 74LV14PW/AU118 is a Hex Inverting Schmitt Trigger integrated circuit produced by Nexperia (formerly part of NXP 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.
The device is pin and function compatible with the 74HC14 and 74HCT14, offering a wide supply voltage range from 1.0 V to 5.5 V. It is optimized for low-voltage applications and accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V.
