The power supply can be any voltage between the minimum and maximum supply voltage rating located in the Recommended Operating Conditions.

Each V_CC terminal should have a good bypass capacitor to prevent power disturbance. For devices with a single supply, a 0.1-μF bypass capacitor is recommended. If there are multiple pins labeled V_CC, then a 0.01-μF or 0.022-μF capacitor is recommended for each V_CC because the VCC pins will be tied together internally. For devices with dual supply pins operating at different voltages, for example V_CC and V_DD, a 0.1-µF bypass capacitor is recommended for each supply pin. 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 should be installed as close to the power terminal as possible for best results.
