Overview
The 74LVC126APW-Q100J is a quad buffer/line driver with 3-state outputs, manufactured by Nexperia USA Inc. This device is part of the 74LVC family, known for its low-voltage CMOS logic and high performance. 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. This makes it suitable for use in a variety of applications, including mixed 3.3 V and 5 V environments, due to its 5 V tolerant input/outputs.
The device is fully specified for partial power-down applications and includes IOFF circuitry to prevent backflow current when powered down. It also offers overvoltage tolerant inputs up to 5.5 V and operates within a wide supply voltage range from 1.2 V to 3.6 V, making it versatile for different system requirements.
