Overview
The 74LVC139PW/AU118, produced by NXP USA Inc., is a dual 2-to-4 line decoder/demultiplexer. This component is designed to decode two binary weighted address inputs (nA0, nA1) into four mutually exclusive outputs (nY0 to nY3). Each decoder features an enable input (nE) that, when set to HIGH, forces all outputs to HIGH, allowing for demultiplexing applications. The device is compatible with both 3.3 V and 5 V logic levels, making it suitable for use in mixed voltage environments.
