ABSOLUTE MAXIMUM RATINGS*

RECOMMENDED DC OPERATING CONDITIONS

AC TEST CONDITIONS

*Stress greater than 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 conditions greater

than those indicated in the operational sections of this specification is not

implied. Exposure to absolute maximum rating conditions for extended

periods may affect reliability.
