4000 Series Logic ICs: The 4051 8-channel analog multiplexer/demultiplexer IC
Playing around with 4000 series logic ICs, this is the 4051 an 8-channel analog multiplexer/demultiplexer. It takes 3bit binary select input which determines the seledcted input/output and the common input/output is used to input an analog signal or output signals coming from the selectable inputs.
Great if you want to expand the analog ability of your Arduino or other micro controller.
It turns out that 'Likes' and 'Shares' actually help the channel so, if you want to, please click the thumbs up or share the video.
