Overview
The 74HC126D-Q100J, produced by Nexperia USA Inc., is a quad buffer/line driver with 3-state outputs. This integrated circuit is part of the 74HC and 74HCT family, known for their high performance and versatility in various electronic applications. The device features four independent buffers, each with a 3-state output controlled by the output enable inputs (nOE). When nOE is LOW, the outputs assume a high-impedance OFF-state, allowing for flexible control over the output lines.
