Product data sheet

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 that enable the

use of current limiting resistors to interface inputs to voltages in excess of VCC.
