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
- 16 Channels – Select any of 16 analogue inputs/outputs with 4 digital control pins

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 (mux) is a chip or circuit that selects one of several input signals and routes it to a single shared output, with select lines choosing which input is connected; running the same idea in reverse, to send one input to a chosen output, gives a demultiplexer. Multiplexers let a single controller or line work with several signals or devices that would otherwise clash on a shared connection.
