A. Decoupling capacitors must be placed as closed as possible to the power terminal. Choose the ground located
closest to the power pin for each decoupling capacitor. In case of interconnecting powers, first insert the decoupling
capacitor and then interconnect the powers.
B. The decoupling capacitor value depends on the board characteristics.
