74AHC139-Q100; 74AHCT139-Q100

Dual 2-to-4 line decoder/demultiplexer

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 (nY0 to nY3). 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.
