Power Decoupling Recommendations:
Bypass caps must be used on power pins. High frequency
ceramic (surface mount is recommended) 0.1 µF in parallel
with 0.01 µF at the power supply pin. A 10 µF or greater
tantalum or electrolytic should be connected at the power
entry point on the printed circuit board.
