Overview
The 74HC125D/AUJ, produced by NXP USA Inc., is a quad buffer/line driver with 3-state outputs. This integrated circuit is part of the 74HC family, known for its CMOS technology, which offers low power dissipation and high noise immunity. The device is designed to operate over a wide supply voltage range from 2.0 V to 6.0 V, making it versatile for various applications. The 3-state outputs are controlled by the output enable inputs (nOE), allowing the outputs to assume a high impedance OFF-state when nOE is HIGH. This feature is particularly useful in bus-oriented systems where multiple devices need to share the same bus lines.
