🛠️ Integration Tips for Arduino / Raspberry Pi

• Power the IC within your system’s logic voltage domain (e.g., 3.3 V or 5 V). When powered above a microcontroller’s I/O voltage, use proper level shifting.
• Decouple the supply with a 100 nF capacitor close to the IC’s VDD and VSS pins for stable operation.
• Tie any unused inputs to a defined logic level (VDD or VSS) to minimize noise and power consumption.
• For inverter functionality, connect both inputs of a NAND gate together.
• Suitable for breadboard prototyping and through‑hole assembly in electronics modules.

Whether you are building logic blocks for a microcontroller project, creating discrete CMOS logic circuits, or designing reliable control systems, the CD4011 delivers dependable performance with broad voltage compatibility and easy integration.
