Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions. Extended exposure to stresses above the recommended
operating conditions may affect device reliability so that any test which is stressing the parts to these levels is not
recommended. The absolute maximum ratings are stress ratings only. T
