Note1)

Note2)

All voltages are relative to VSS = 0V reference.

Do not exceed the absolute maximum ratings, otherwise the stress may cause a permanent damage to the IC. It is

also recommended that the IC be used in the range specified in the DC electrical characteristics, or the electrical

stress may cause mulfunctions and impact on the reliability.
