Overview
The 74HC126DB,112 is a quad buffer/line driver with 3-state outputs, manufactured by Nexperia USA Inc. This integrated circuit is part of the 74HC series and is designed to provide high-performance buffering and line driving capabilities. The device features four independent buffers, each with a 3-state output controlled by an output enable input (nOE). When nOE is LOW, the outputs assume a high-impedance OFF-state, allowing for flexible control over the output lines.
