CD74HC4067 16-Channel Analog Multiplexer / Demultiplexer
This very convenient breakout board enables you to make use of the very capable CD74HC4067 Analog Multiplexer IC for your bread board projects.
One of the 16 possible input channels is selected by 4 address lines (binary), and the input signal is routed through to the output pin.
With this module you can measure up to 16 analog values by using only 1 analog input pin on a micro controller. All you need to do is selecting which one of the 16 input values you want to see on the output pin.
Since this chip works in both directions, you can also use it to send 1 analog output signal to 16 different, adressable outputs.
The wide operating voltage range of 2 to 6V makes this chip the perfect for 3.3V and 5V micro controller applications.
