    • The 74139 is a dual 2 – 4 line decoder with a demultiplexer in the 7400 series. Each side of the IC is a decoder with an active low enable from a 2-bit address to four active low signals. The two decoders can be wired independently, or a /Y from one decoder can be wired to the /E on the other to calculate more complex combinational logic functions.
