AVSS – 0.3 V to AVDD + 0.3 V Lead Temperature, Soldering Digital Inputs to DGND2 . –0.3 V to DVDD + 0.3 V Vapor Phase (60 sec) . +215°C Digital Outputs to DGND . –0.3 V to DVDD + 0.3 V Infrared (15 sec) . +220°C Operating Temperature Range NOTES 1 Commercial Plastic (B Versions) . –40°C to +85°C Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional Storage Temperature Range . –65°C to +150°C operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2Transient currents of up to 100 mA will not cause SCR latch-up.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
WARNING!
accumulate on the human body and test equipment and can discharge without detection. Although these devices feature proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
