Overview
The 74LVC125APW/AU118, produced by NXP USA Inc. (now part of Nexperia), is a quad buffer/line driver with 3-state outputs. This device is designed to operate in mixed 3.3 V and 5 V environments, making it versatile for various electronic systems. It features output enable inputs (nOE) that control the 3-state outputs, allowing the outputs to assume a high impedance OFF-state when nOE is HIGH. The device is also equipped with Schmitt-trigger action at all inputs, enhancing its tolerance to slower input rise and fall times.
