Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product

performance may not be indicated by the Electrical Characteristics if operated under different conditions.

4. The maximum Input Voltage of the ELECTRICAL CHARACTERISTICS is 5.25 V. In case of exceeding this specification, the IC must be

operated on condition that the Input Voltage is up to 5.5 V and the total operating time is within 500 hrs.
