🔀 CD74HC4067 16-Channel Analog/Digital Multiplexer Module

The CD74HC4067 is a 16-channel analog/digital multiplexer/demultiplexer that allows multiple signals to be connected to a single microcontroller input/output.
Perfect for saving GPIO pins and efficiently handling multiple sensors or inputs.

🛡️ Features & Safety

• 🔄 16 selectable analog or digital channels
• 📡 Controlled via 4 selection pins (S0–S3)
• 🔌 Supports both 3.3V and 5V logic signals
• 📊 Low ON resistance (~70 Ω typical)
• ⚡ Wide operating voltage: 2V to 10V

📦 Compact & Convenient

• Module based on CD74HC4067 high-speed chip
• Clearly labeled pins for easy wiring
• Compact size, ideal for prototyping

🛠️ Applications

• 🔧 Expanding analog inputs for Arduino/ESP32
• 🎛️ Reading multiple sensors (joysticks, potentiometers, etc.)
• 📡 Digital signal switching
• 🧪 Embedded systems and prototyping

⚠️ Notes

• ❗ The multiplexer does not amplify the signal, it only switches
• 🔋 Ensure proper voltage compatibility with your system
• ⚡ Only one channel active at a time
