The power supply can be any voltage between the minimum and maximum supply voltage rating located in the GUID-0F8B1753-775E-4E6C-BC50-F6B31D197853.html#GUID-0F8B1753-775E-4E6C-BC50-F6B31D197853. 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-53CF40CE-53E4-47FF-9AE9-3766CDB5380F.html#LAYOUTEXAMPLE.
