Note1) Absolute maximum ratings represent the values which cannot be exceeded for any length of time.

Note2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high

voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
