The power supply can be any voltage between the minimum and maximum supply voltage rating located in the GUID-21AD65E0-3428-4493-BB6D-29EA624FF219.html#GUID-21AD65E0-3428-4493-BB6D-29EA624FF219. 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-71FD8B93-9F6F-40DB-9AB0-2261E18C213A.html#LAYOUTEXAMPLE.
