8.1 Power Supply Recommendations

The power supply can be any voltage between the minimum and maximum supply voltage rating located in the Section 5.2 table. The total current through Ground or VCC must not exceed ±70 mA as per Section 5.1 table.

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