In previous posts we showed some examples for the 4067 16-Channel multiplexer – http://www.piclearning.net/132/chipkit-uno-and-4067-led-output-example.php The HCF4051 device is a monolithic integrated circuit fabricated in MOS (metal oxide semiconductor) technology available in SO-16 and PDIP-16 packages. The HCF4051 analog multiplexer/demultiplexer is a digitally…
