Absolute Maximum Voltage Rating
Warning: For proper and reliable operation in adherence with this data sheet, the device should not exceed the recommended operating voltages
in Table 16. The absolute maximum operating voltages in Table 21 are offered to provide guidelines for voltage excursions outside the recommended
voltage ranges. Device functionality is not guaranteed at these conditions and sustained operation at these values or any exposure to voltages outside
the maximum range may adversely affect device functionality and reliability.
