IC Usage Considerations

Notes on handling of ICs

[1] The absolute maximum ratings of a semiconductor device are a set of ratings that must not be

exceeded, even for a moment. Do not exceed any of these ratings.

Exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result

injury by explosion or combustion.

[2] Do not insert devices in the wrong orientation or incorrectly.

Make sure that the positive and negative terminals of power supplies are connected properly.

Otherwise, the current or power consumption may exceed the absolute maximum rating, and

exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result

injury by explosion or combustion.

In addition, do not use any device that is applied the current with inserting in the wrong orientation

or incorrectly even just one time.
