About this product
A breakout board for the 74HC4067 CMOS analog multiplexer, which routes one of 16 analog or digital channels to a single common pin using four select lines. It is commonly used to read many sensors with a microcontroller that has few analog inputs.

Frequently asked questions
How do I wire it to a microcontroller?
Connect S0 to S3 to digital pins to select the channel, connect the common SIG pin to an analog input, tie EN to GND to enable the multiplexer, and power VCC and GND.
What voltage can the channels handle?
Analog signals must stay between GND and VCC. Applying a voltage above VCC or below GND can damage the multiplexer, so keep the signal within the supply rails.
