🔌 Integration Tips for Arduino and Raspberry Pi

• Power the IC at 3.3 V for Raspberry Pi or 5 V for many Arduino boards; keep all signals within the selected VCC rails.
• Add a 0.1 µF decoupling capacitor close to VCC–GND for stable operation.
• Tie any unused inputs to VCC or GND (do not leave floating).
• For slow edges or noisy signals, consider a Schmitt-trigger inverter (74HC14) instead of the 74HC04.

Whether you’re building microcontroller-based projects, experimenting with electronics modules, or designing robust digital logic stages, the 74HC04 delivers reliable voltage-level inversion and fast switching performance in a familiar, easy-to-use package.
