The SparkFun Analog/Digital MUX CD74HC4067 breakout board includes a 16-channel multiplexer/demultiplexer for analog and digital signals. It routes the common SIG pin to one of the 16 CHANxx channels, with connections working in both directions. Four digital outputs on the S0–S3 address select pins select the channel, allowing up to 16 sensors to be connected to a system using just five pins in total.
The board can also route TTL-level serial data between multiple devices or be used in setups for I2C and SPI with additional boards. The enable pin fully disconnects the common pin when driven high. The internal switches support bidirectional operation and break-before-make switching to limit crosstalk between channels.
