Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.

Caution 2) 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.
