Overview
The 74LVC126APW/AU118 is a quad buffer/line driver produced by NXP USA Inc., now part of Nexperia. This device is designed to operate in mixed 3.3 V and 5 V environments, making it versatile for various electronic systems. It features 3-state outputs controlled by the output enable inputs (nOE), allowing the outputs to assume a high impedance OFF-state when nOE is HIGH. The device is fully specified for partial power-down applications and includes overvoltage tolerant inputs up to 5.5 V.
