1. General description
The 74AHC139-Q100; 74AHCT139-Q100 is a high-speed Si-gate CMOS device and is
pin compatible with Low-power Schottky TTL (LSTTL). It is specified in compliance with
JEDEC standard No. 7A.
The 74AHC139-Q100; 74AHCT139-Q100 is a high-speed, dual 2-to-4 line
decoder/demultiplexer. This device has two independent decoders. Each decoder accepts
two binary weighted inputs (nA0 and nA1) and provides four mutually exclusive active
LOW outputs (nY
0tonY3). Each decoder has an active LOW enable input (nE). When nE
is HIGH, every output is forced HIGH. The enable input can be used as the data input for
a 1-to-4 demultiplexer application.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
