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.
