The CD74HC4067 breakout board functions as a 16-channel multiplexer and demultiplexer for analog and digital signals. It connects the common SIG pin to one of the CHANxx channels, and the connections work in both directions.
Channels are controlled via the S0–S3 select pins, which are supplied with the binary address of the channel. This allows up to 16 sensors to be connected to the system using 5 pins. The board can also route TTL-level serial data or be used in I2C and SPI communication setups. When driven high, the enable pin disconnects the common pin from all channels.
