Overview
The 74HC125PW/S490118, produced by NXP USA Inc., is a quad buffer/line driver with 3-state outputs. This integrated circuit is part of the 74HC family and is designed to provide low power dissipation and high noise immunity, making it suitable for a wide range of electronic applications. The device features four independent buffers, each with a 3-state output controlled by the output enable inputs (nOE), allowing the outputs to be set to a high impedance OFF-state when nOE is HIGH.
