Overview
The 74LVC125APW-Q100 is a quad buffer/line driver produced by NXP USA Inc. This device is part of the LVC (Low-Voltage CMOS) family and is designed for high-performance, low-power, and low-voltage applications. It features 3-state outputs controlled by the output enable input (nOE), allowing the outputs to assume a high-impedance OFF-state when nOE is HIGH. This component is particularly useful in mixed 3.3 V and 5 V environments due to its 5 V tolerant inputs and outputs.
