Overview
The 74HCT126DB,118 is a quad buffer/line driver with 3-state outputs produced by Nexperia USA Inc. This integrated circuit is part of the 74HCT series and is designed to provide reliable and efficient signal buffering and driving capabilities. The device features four independent buffers, each with a 3-state output controlled by an output enable input (nOE). When the nOE input is LOW, the outputs assume a high-impedance OFF-state, allowing for flexible control over the output signals.
