Electrical Characteristics

Absolute Maximum Ratings

C = commercial......................................................0°C to 70°C

I = industrial ........................................................-40°C to 85°C

Storage Temperature .................................... -65°C to + 150°C

Voltage on VCC to VSS (standard voltage) .........-0.5V to + 6.5V

Voltage on VCC to VSS (low voltage)..................-0.5V to + 4.5V

Voltage on Any Pin to VSS..........................-0.5V to VCC + 0.5V

Power Dissipation .............................................................. 1 W

Note:

Stresses at or above those listed under “Absolute

Maximum Ratings” may cause permanent damage

to the device. This is a stress rating only and func-

tional operation of the device at these or any other

conditions above those indicated in the operational

sections of this specification is not implied. Expo-

sure to absolute maximum rating conditions may

affect device reliability.

Power dissipation value is based on the maximum

allowable die temperature and the thermal resis-

tance of the package.
