Overview
The 74LVC139PW,112 is a dual 2-to-4 line decoder/demultiplexer IC manufactured by Nexperia USA Inc. This component is part of the 74LVC series and is designed for use in a variety of digital logic applications. It decodes two binary weighted address inputs (nA0, nA1) to four mutually exclusive outputs (nY0 to nY3), making it suitable for both decoding and demultiplexing functions. The device features an enable input (nE) that can be used to force all outputs high, which is useful in demultiplexer applications. The 74LVC139PW,112 is packaged in a 16-pin TSSOP (Thin Shrink Small Outline Package) and is RoHS compliant.
