Overview
The 74LVC125APW/S400118 is a quad buffer/line driver produced by NXP USA Inc. This component is part of the LVC (Low Voltage CMOS) series and is designed to operate in a wide range of supply voltages from 1.2 V to 3.6 V. It features 3-state outputs controlled by the output enable inputs (nOE), allowing for high impedance OFF-state when nOE is HIGH. This device is particularly useful in mixed 3.3 V and 5 V environments due to its 5 V tolerant input/outputs.
