Electrical Characteristics

2.1

Absolute Maximum Ratings

Absolute Maximum Ratings which may not be exceeded to the device without causing

permanent damage or degradation. Exposure to these values for extended periods may

effect device reliability. If the device is operated beyond the range of Operating

Conditions and Characteristics functionality is not guaranteed. All voltages given within

this data sheet are referred to

VEE if not otherwise mentioned.
