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 at any other condition above those indicated in the operation sections of this specification

is not implied.

3. 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 any voltages larger than the rated maxima.

4. Parameters are valid over operating temperature range unless otherwise specified. See ordering code table for applicable temperature

range and operating supply range.
