The CD74HC4067 CMOS multiplexer breakout board is designed to handle both analog and digital signals. The key requirement is that the signal voltage must not exceed the VDC supply voltage of the board for safe and optimal performance.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I select a specific channel on the CD74HC4067 breakout board?\u003c\/h4\u003e\n\u003cp\u003eA: Channel selection is controlled via 4 digital address pins labeled S0–S3. By sending the binary address of the desired channel (0–15) to these pins from your microcontroller, the board routes the SIG (common) pin to the corresponding channel (C0–C15).
