Note 1: When a voltage over the absolute maximum rating is applied, the characteristics of the device may be drastically
aggravated or the chip may be broken.
Note 2: It is recommended to use the device within the range of electrical characteristics. When it is used out of the range, the
operations and the reliability of the device cannot be guaranteed.
