Datasheet
●Operational Notes
(1) Described numeric values and data are design representative values, and the values are not guaranteed.
(2) We believe that application circuit examples are recommendable, however, in actual use, confirm characteristics further
sufficiently. In the case of use by changing the fixed number of external parts, make your decision with sufficient margin in
consideration of static characteristics and transition characteristics and fluctuations of external parts and our LSI.
(3) Absolute Maximum Ratings
If the absolute maximum ratings such as supply voltage and operating temperature and so forth are exceeded, LSI may
be destructed. Do not impress voltage and temperature exceeding the absolute maximum ratings. In the case of fear
exceeding the absolute maximum ratings, take physical safety countermeasures such as fuses, and see to it that
conditions exceeding the absolute maximum ratings should not be impressed to LSI.
(4) GND electric potential
Set the voltage of GND terminal lowest at any operating condition. Make sure that each terminal voltage is not lower than
that of GND terminal in consideration of transition status.
(5) Heat design
In consideration of allowable loss in actual use condition, carry out heat design with sufficient margin.
(6) Terminal to terminal short circuit and wrong packaging
When to package LSI onto a board, pay sufficient attention to LSI direction and displacement. Wrong packaging may
destruct LSI. And in the case of pin short between LSI terminals and terminals, terminals and power source, terminals and
GND owing to unconnect use, LSI may be destructed.
(7) Using this LSI in a strong electromagnetic field may cause malfunction, therefore, evaluate the design sufficiently.
