Overview
The 74LVC1G126GW, produced by Nexperia (formerly part of NXP USA Inc.), is a single non-inverting buffer/line driver with a 3-state output. This device is designed to operate within a wide supply voltage range from 1.65 V to 5.5 V, making it versatile for use in mixed 3.3 V and 5 V environments. The 3-state output is controlled by the output enable input (OE), allowing the output to enter a high-impedance state when OE is LOW. This feature is particularly useful for partial power-down applications, where the IOFF circuitry prevents damaging backflow current through the device when it is powered down.
