CHARACTERISTICS

Absolute Maximum Ratings*

Supply Voltage ......................................................+7V

Voltage on Any Pin with Respect to Supplies:

..................................................VSS -0.3 to VDD +0.3V

Operating Temperature ......................-40Â°C to +125Â°C

Storage Temperature Range ..............-55Â°C to +150Â°C

*Stresses above those listed under "Absolute Maximum Rat-

ings" may cause permanent damage to the device. These are

stress ratings only and functional operation of the device at

these or any other conditions above those indicated in the

operation sections of the specifications is not implied. Expo-

sure to Absolute Maximum Rating conditions for extended

periods may affect device reliability.
