CD74HC4067 16-Channel Analog Digital Multiplexer Breakout Board Module


This is a breakout board for the handy CD74HC4067 16-channel analog / digital multiplexer / demultiplexer. This chip is like a rotary switch - it internally routes the common pin (COM in the diagram, SIG on the board) to one of the 16 channel pins (CHANxx). It works with digital and analog signals (the voltage cannot be higher than VCC), and the connections work in both directions. To control it, connect 4 digital outputs to the chip's address selection pins (S0-S3), and send it the binary address of the desired channel (see the datasheet for details). This allows you to connect up to 16 sensors to your system using just 5 pins!
