HD74HC4051

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.
