RECOMMENDED OPERATING CONDITIONS
(ELECTRICAL CHARACTERISTICS)
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating conditions.
The semiconductor devices cannot operate normally over the recommended operating conditions, even if
when they are used over such conditions by momentary electronic noise or surge.
And the semiconductor devices may receive serious damage when they continue to operate over the
recommended operating conditions.
