（１）Absolute maximum ratings

When applied voltage (VDD and VIN), and the operating temperature range (Topr) and the like it exceeds absolute maximum rating, there is a possibility of

destroying, Because it cannot specify destructive mode such as short circuit or opening, when special mode which exceeds absolute maximum rating is

supposed, that physical safety measure such as a fuse should be implemented.

（２）Recommendation operating range

If it is this range, it is the range which almost can obtain the quality of according to expectation. Concerning electric quality ，being something which is

guaranteed

under condition of each item. Even inside the recommendation operating range, voltage, temperature characteristic is shown.

（３）About the opposite connection of the power source connector

There is a possibility of destroying LSI with the opposite connection to the power source connector. Please administer the measure such as the diode is

inserted between power source and the power source terminal of LSI outside as the protection for opposite connection destruction.

（４）About the power source line

At the time of designing the baseplate pattern, as for wiring of the power source/GND line, please make sure to become low impedance. At that time, even

digital type power source and analog type power source being the same electric potential, please separate digital type power source pattern and analog

type power source pattern, control the turning of digital noise to the analog power source due to the common impedance of wiring pattern. Concerning the

GND line, please consider the similar pattern design. In addition, concerning all power source terminals of LSI, the condenser is inserted between power

source and the GND terminal, in the case of electrolysis condenser use, please decide constant with sufficient verification in regard to the fact of without

being problem in qualities of the condenser which is used, such as the capacity pulling out happens in low temperature.

As for electric potential of the GND terminal regarding what ever working condition, please make sure to become lowest electric potential. In addition,

please really verify that does not have the terminal which becomes electric potential below GND include transient phenomenon

（６）About the short circuit between the terminal and error installing

The occasion where you install in the set baseplate, please pay attention to the direction and the position gap of LSI sufficiently. when you install with

mistake, there is a possibility of LSI destroying. In addition, there is a possibility of destruction concerning when it short-circuits e.g. due to the foreign

material enters between the terminal and between terminal and power source and GND.

（７）About the operation in the strong electromagnetic field

As for the use in the strong electromagnetic field, being to be a possibility of doing the malfunction, please note.

（８）About the testing with the set baseplate

When inspecting with the set baseplate, the condenser is connected to the LSI terminal whose impedance is low, because there is a possibility of stress

depending on LSI, please be sure to do discharge in every process. In addition, when installing and removing the tool in inspection process, by all means

with power source as off to connect, to inspect, to remove. Furthermore, As a static electricity measure, please note to administer the earth and the

conveyance and preservation in the case of assemble process sufficiently.

（９）About each input terminal

With respect to the structure of LSI, the parasitic element is formed inevitably by the relationship of electric potential. It causes the interference of circuit

operation due to the fact that the parasitic element operates, the malfunction, even can become cause of destruction. Therefore, e.g., the voltage which is

lower than GND in the input terminal is impressed, please note sufficiently not to do the method where the parasitic element operates. In addition, When

not impress power supply voltage in LSI, please do not impress voltage in the input terminal. Furthermore, when power supply voltage is impressed even,

as for each input terminal, please make voltage below power supply voltage or within guaranteed performance of electric quality.

（１０）About GND wiring pattern

When there are both small signal GND and a heavy-current GND, it separates small signal GND pattern from heavy-current GND pattern, in order that the

pattern wiring and the voltage change caused by large current do not change the voltage of small-signal GND, it is recommended to carry out the one-point

grounding at the reference point of set.. Please be careful of not to fluctuate the GND wiring pattern of external parts

（１１）When in the external condenser, the ceramic condenser is used, please decide the constant on the consideration of the nominal capacity decrease

caused by direct current bias and the change of the capacity due to temperature etc.
