74HC139-Q100; 74HCT139-Q100
Dual 2-to-4 line decoder/demultiplexer
Rev. 1 — 19 June 2014
Product data sheet
1. General description
The 74HC139-Q100; 74HCT139-Q100 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.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
