The 74HC139PW is a 2-to-4 dual Decoder/Demultiplexer decodes two binary weighted address inputs nA0, nA1 to four mutually exclusive outputs nY0\ to nY3\\. Each decoder features an enable input nE\\. When nE\ is high all outputs are forced high. The enable input can be used as the data input for a 1-to-4 demultiplexer application. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
