The power supply can be any voltage between the minimum and maximum supply voltage rating (see Recommended Operating Conditions).

Each V_CC pin must have a good bypass capacitor to prevent power disturbance. TI recommends 0.1 µF for devices with a single supply. If there are multiple V_CC pins, then TI recommends 0.01 µF or 0.022 µF for each power pin. It is acceptable to parallel multiple bypass capacitors to reject different frequencies of noise. A 0.1 µF and a 1 µF are commonly used in parallel. The bypass capacitor must be installed as close to the power pin as possible for best results.
