Overview
The 74HCT125PW-Q100J is a quad buffer/line driver produced by Nexperia USA Inc. This component is part of the 74HCT series and is designed to provide high-speed buffering and line driving capabilities with 3-state outputs. The device is controlled by output enable inputs (nOE), which allow the outputs to assume a high impedance OFF-state when nOE is HIGH. This feature is particularly useful in applications where signal isolation or bus management is required.
The 74HCT125PW-Q100J is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for use in automotive applications. It operates over a wide supply voltage range from 2.0 V to 6.0 V and is known for its CMOS low power dissipation and high noise immunity.
