Fig.55 Application circuit example(BU7344HFV)

* For VDD and VSS, insert a bypass capacitor of approx. 0.1μF as close as possible to the pin.Bypass capacitors with

good high-frequency characteristics are recommended. Even though we believe that the typical application circuit is

worth of a recommendation, please be sure to thoroughly recheck the characteristics before use.
