6 / 37 page ![]() 6 Specifications 6.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted)(1) (2) MIN MAX UNIT Voltage VCC1, VCC2 –0.5 6 V SDA1, SCL1 –0.5 VCC1 + 0.5(3) SDA2, SCL2 –0.5 VCC2 + 0.5(3) IO Output current SDA1, SCL1 0 20 mA SDA2, SCL2 0 100 TJ(MAX) Maximum junction temperature 150 °C Tstg Storage temperature –65 150 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values here within are with respect to the local ground pin (GND1 or GND2) and are peak voltage values. (3) Maximum voltage must not exceed 6 V. 6.2 ESD Ratings VALUE UNIT V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) Bus pins ±8000 V All pins ±4000 Charged-device model (CDM), per JEDEC specification JESD22- C101(2) ±1500 (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 6.3 Recommended Operating Conditions MIN MAX UNIT VCC1, VCC2 Supply voltage 3 5.5 V VSDA1, VSCL1 Input and output signal voltages, side 1 0 VCC1 V VSDA2, VSCL2 Input and output signal voltages, side 2 0 VCC2 V VIL1 Low-level input voltage, side 1 0 0.5 V VIH1 High-level input voltage, side 1 0.7 × VCC1 VCC1 V VIL2 Low-level input voltage, side 2 0 0.3 × VCC2 V VIH2 High-level input voltage, side 2 0.7 × VCC2 VCC2 V IOL1 Output current, side 1 0.5 3.5 mA IOL2 Output current, side 2 0.5 35 mA C1 Capacitive load, side 1 40 pF C2 Capacitive load, side 2 400 pF fMAX Operating frequency(1) 1 MHz TA Ambient temperature –40 125 °C TJ Junction temperature –40 136 °C TSD Thermal shutdown 139 197 °C (1) This represents the maximum frequency with the maximum bus load (C) and the maximum current sink (IO). If the system has less bus capacitance, then higher frequencies can be achieved.
