Absolute Maximum Ratings Vcc to GND……………….………….…….-0.3V to +6V DXP1, DXP2 to GND……………0.3V to (Vcc + 0.3V) DXN to GND…………………………...-0.3V to +0.8V SMBCLK, SMBDATA, ALERT to GND.-0.3V to +6V SMBDATA, ALERT Current…………-1mA to +50mA DXN Current……………………………..…………±1mA ESD Protection (SMBCLK, SMBDATA, ALERT , hu- man body model)….…………………………….4000V ESD Protection (other pins, human body model).2000V Continuous Power Dissipation (TA= +70°C) SSOP (de-rate 8.30mW/°C above +70°C)…….………667mW Operating Temperature Range………-10°C to +85°C Junction Temperature…………………....+150°C Storage temperature Range…………..-65°C to +165°C Lead Temperature (soldering,10sec)………….+300°C 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 in the opera- tional sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Electrical Characteristics (Vcc = + 5V, TA = 60°C, unless otherwise noted.)
