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 conditions other than those described in the AC and DC Electrical Characteristics section

of this specification is not implied.

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

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

3. Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to VSS unless otherwise

noted.

Electrical Deviations from Commercial Specifications for Extended Temperature Range

DC and AC parameters not included here are the same as in the commercial temperature range table.
