Overview
The 74LVC126ABQ,115 is a quad buffer/line driver integrated circuit produced by Nexperia USA Inc. This device is designed with 3-state outputs controlled by the output enable inputs (nOE), allowing the outputs to assume a high impedance OFF-state when nOE is LOW. It is particularly useful in mixed 3.3 V and 5 V environments due to its 5 V tolerant input/outputs and Schmitt-trigger action at all inputs, which enhances noise immunity and tolerance to slower input rise and fall times.
The 74LVC126ABQ,115 is part of the 74LVC series, known for its low power consumption, high-speed operation, and compliance with various JEDEC standards. It is packaged in a 14-DHVQFN (2.5x3) exposed pad package, making it suitable for surface mount designs.
