CHARACTERISTICS

ABSOLUTE MAXIMUM RATINGS †

VIN to GND........................................................-0.5V to +45V

VDD to GND, VDD 1-3 to GND..........................--0.3V to +10V

All other pins to GND .............................-0.3V to (V

DD + 0.3V)

Operating temperature ..................................-40°C to +125°C

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

Continuous power dissipation (TA = +25°C).............5000 mW

† Notice: Stresses above those listed under “Absolute Maxi-

mum Ratings” may cause permanent damage to the device.

This is a stress rating only and functional operation of the

device at those or any other conditions, above those indi-

cated in the operational listings of this specification, is not

implied. Exposure to maximum rating conditions for extended

periods may affect device reliability.
