Simply connect the 4 select lines (S0–S3) and the common SIG pin to your microcontroller's digital and analog I\/O pins.\u003c\/p\u003e\n\u003ch4\u003eQ: Can this module handle both analog and digital signals?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The CD74HC4067 is a bidirectional multiplexer\/demultiplexer, meaning it can route both analog and digital signals in either direction (input or output). This makes it extremely versatile for sensor arrays, signal switching, and digital I\/O expansion applications.\u003c\/p\u003e\n\u003ch4\u003eQ: How many channels can I select, and how do I control them?\u003c\/h4\u003e\n\u003cp\u003eA: The module features 16 independent channels (C0–C15). You select a specific channel by setting a 4-bit binary address on the S0, S1, S2, and S3 control pins. For example, setting S0=LOW, S1=LOW, S2=LOW, S3=LOW selects channel C0, while S0=HIGH, S1=HIGH, S2=HIGH, S3=HIGH selects channel C15.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I daisy-chain multiple CD74HC4067 modules together?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. Each module includes an active-low enable (EN) pin. By using a digital output pin from your microcontroller to enable or disable individual modules, you can chain multiple boards together to expand to 32, 48, or more channels as needed for your project.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What microcontrollers is the CD74HC4067 breakout board compatible with?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The CD74HC4067 multiplexer breakout board is compatible with a wide range of microcontrollers including Arduino (Uno, Mega, Nano), Raspberry Pi, ESP8266, ESP32, and most 3.3V or 5V development boards.
