Overview
The 74HCT139DB-Q100J is a dual 2-to-4 line decoder/demultiplexer integrated circuit produced by Nexperia USA Inc. Although this specific part is now obsolete and no longer manufactured, it was designed to decode two binary weighted address inputs to four mutually exclusive outputs. It features an enable input that can be used to force all outputs high or to function as a data input for a 1-to-4 demultiplexer application. This component was qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for automotive applications.
