Overview
The 74HC125D-Q100J is a quad buffer/line driver with 3-state outputs, manufactured by Nexperia USA Inc. This component is part of the 74HC series and is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for use in automotive applications. It features CMOS low power dissipation, high noise immunity, and a wide supply voltage range from 2.0 V to 6.0 V. The device includes output enable inputs (nOE) that control the 3-state outputs, allowing the outputs to assume a high impedance OFF-state when nOE is HIGH. Inputs are protected with clamp diodes, enabling the use of current limiting resistors to interface with voltages exceeding VCC.
