Overview
The MC74HC139ADG is a dual 1-of-4 decoder/demultiplexer produced by onsemi. This device is part of the high-performance silicon-gate CMOS family and is identical in pinout to the LS139. It consists of two independent 1-of-4 decoders, each decoding a two-bit address to one-of-four active-low outputs. The device also features active-low selects to facilitate demultiplexing and cascading functions.
