1. The thermal limit is set above the maximum thermal rating. It is not recommended to operate the device at temperatures

greater than the maximum ratings for extended periods of time.

Note:

Absolute maximum ratings are those values beyond which damage to the device may occur. Functional

operation under these conditions is not implied. Exposure to absolute maximum rating conditions may affect

device reliability. All values are referred to GND.
