The power supply can be any voltage between the minimum and maximum supply voltage rating located in the Section 6.3.
Each VCC terminal must have a good bypass capacitor to prevent power disturbance. A 0.1-µF bypass capacitor is recommended to be placed close to the VCC terminal. It is acceptable to parallel multiple bypass capacitors to reject different frequencies of noise; 0.1-µF and 1-µF capacitors are commonly used in parallel. The bypass capacitor must be installed as close to the power terminal as possible for best results.
