Absolute Maximum Ratings*

Maximum Supply Voltage ............................ up to 8.5V

Storage Temperature ..........................

-50°Cto125°C

Operating Temperature .........................

-40°Cto85°C

Note: These are stress ratings only. Stresses exceeding the range specified under

²Absolute Maximum Ratings² may

cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed

in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.

²*² Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating Ratings in-

dicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits.

The guaranteed specifications apply only for the test conditions listed.
