ELECTRICAL CHARACTERISTICS

Absolute Maximum Ratings

Ambient temperature under bias (TA)	-40 to + 85	°C
Storage temperature (TST)	-65 to + 150	°C
Voltage on VCC pins with respect to ground (VSS)	-0.5V to 6.5V
Voltage on any pin with respect to ground (VSS)	-0.5V to VCC + 0.5V
Input current on any pin during overload condition	-15mA to +15mA
Absolute sum of all input currents during overload condition	100mA
Power dissipation	1.5W

Note: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage of the de- vice. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rat- ing conditions for longer periods may affect device reliability. During overload conditions (VIN > VCC or VIN < VSS) the Voltage on VCC pins with respect to ground (VSS) must not exceed the values defined by the absolute maxi- mum ratings.
