1. General description

The 74HC139; 74HCT139 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.
