Overview
The 74HCT125D-Q100118 is a quad buffer/line driver with 3-state outputs, manufactured by NXP USA Inc. This component is part of the 74HCT series and is designed to meet the stringent requirements of automotive applications, having been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1).
It features four independent buffers, each with a 3-state output controlled by the output enable inputs (nOE). When nOE is HIGH, the outputs assume a high impedance OFF-state, allowing for flexible control over the output states.
