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.
