1042G–AVR–09/02

Electrical Characteristics

Absolute Maximum Ratings*

Operating Temperature.................................. -55°Cto+125°C

*NOTICE: Stresses beyond those listed under “Absolute

Maximum Ratings” may cause permanent dam-

age to the device. This is a stress rating only and

functional operation of the device at these or

other conditions beyond those indicated in the

operational sections of this specification is not

implied. Exposure to absolute maximum rating

conditions for extended periods may affect

device reliability.
