Overview
The 74LVC139D, produced by Nexperia USA Inc., is a dual 2-to-4 line decoder/demultiplexer integrated circuit. This device 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 HIGH, forces all outputs HIGH, allowing it to function as a 1-to-4 demultiplexer. The 74LVC139D is designed to operate in a wide supply voltage range from 1.2 V to 3.6 V, making it versatile for various applications, including mixed 3.3 V and 5 V environments.
