Overview
The SN74LVC2G14DBVRE4, produced by Texas Instruments, is a dual Schmitt-trigger inverter integrated circuit. This device is part of the LVC (Low-Voltage CMOS) family and is designed to operate over a wide voltage range from 1.65 V to 5.5 V. It features two independent inverters with Schmitt-trigger inputs, which provide hysteresis to improve noise immunity and ensure clean, jitter-free output signals even with slow or noisy input ramps.
