NOTES:

1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and

functional operation of the device at these or any other condition above those indicated in the operation section of this specification is not implied.

2. For operating at elevated temperatures, the device must be derated.

3. This product includes circuitry specifically designed for the protection of its internal devices from damaging effects of excessive static

charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying any voltages larger than the rated maxima.

4. Parameters are valid over specified temperature range.
