Overview
The 74HC139D-Q100J, produced by Nexperia USA Inc., is a dual 2-to-4 line decoder/demultiplexer integrated circuit. This component decodes two binary weighted address inputs (nA0, nA1) to four mutually exclusive outputs (nY0 to nY3). Each decoder features an enable input (nE) that, when set HIGH, forces all outputs to HIGH, allowing it to function as a 1-to-4 demultiplexer. The device is designed to operate within a wide voltage range and is suitable for various applications, including memory decoding, data routing, and code conversion.
