The power supply can be any voltage between the minimum and maximum supply voltage rating located in the Recommended Operating Conditions. Each VCC terminal should have a bypass capacitor to prevent power disturbance. A 0.1-μF capacitor is recommended for this device. It is acceptable to parallel multiple bypass caps to reject different frequencies of noise. The 0.1-μF and 1-μF capacitors are commonly used in parallel. The bypass capacitor should be installed as close to the power terminal as possible for best results, as shown in GUID-DECCF2F7-097A-46BC-A7F7-B0A7F90B9626.html#LAYOUTEXAMPLE.
