HD74HC4051
8-Channel Analog Multiplexer Demultiplexer
Description
This device connects together the outputs of 8 switches, thus achieving an 8 Channel Multiplexer. The
binary code placed on the A, B, and C select lines determine which one of the eight switches in "on", and
connects one of the eight inputs to the common output.
