Overview
The 74HC125DB,112 is a quad buffer/line driver with 3-state outputs, manufactured by NXP USA Inc. This component is part of the 74HC and 74HCT family, known for its versatility and reliability in various electronic circuits. The device 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, making it suitable for applications requiring output control.
