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. (2) The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed. (3) The package thermal impedance is calculated in accordance with JESD 51-7. (4) The package thermal impedance is calculated in accordance with JESD 51-5. MIN MAX UNIT VCC Supply voltage 2.3 5.5 V SCL, SDA 0.7 × V CC 6 VIH High-level input voltage V A2–A0, INT3–INT0 0.7 × V CC VCC + 0.5 SCL, SDA –0.5 0.3 × V CC VIL Low-level input voltage V A2–A0, INT3–INT0 –0.5 0.3 × V CC TA Operating free-air temperature –40 85 °C (1) All unused inputs of the device must be held at VCC or GND to ensure proper device operation.
