The Texas Instruments CD74HC4067 is a 16-channel analogue multiplexer/demultiplexer IC. It allows you to route one of 16 analogue signals to a single common pin (or vice versa) using just 4 digital control lines plus an enable pin — effectively expanding a single ADC channel to read from 16 sources.
This is the bare IC in a 24-pin SSOP package. A 28-pin SSOP-to-DIP adapter board is recommended for breadboard prototyping.
Key Features

Jargon buster
Plain-language definitions for the technical terms used above.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- multiplexer
- A multiplexer is a chip or board that lets one controller switch between several devices that would otherwise conflict on the same bus. It matters here because multiple modules with the same I2C address cannot normally share one I2C bus without extra hardware.
