ABSOLUTE MAXIMUM RATINGS

over operating free-air temperature range (unless otherwise noted)

(1)

RANGE

Supply voltage range

–0.3 V to 2.75 V

Open-drain I/O pins

–0.3 V to 6 V

Input voltage range to all other pins

Operating free-air temperature range

–40°C to 85°C

Storage temperature range

–65°C to 150°C

(1)

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
