* Exception: The “VIN < VDD+1.0V” restriction does not apply to the SCL and SDA inputs.
Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating
only, and the functional operation of the device at these or any other conditions above those listed in the operational section of this
specification is not implied. Exposure to absolute maximum ratings conditions for extended periods may affect device reliability.

Notes
1. SCL toggling between V_DD-0.3V and V_SS, other inputs V_SS or V_DD-0.3V.
2. SCL = SDA = V_DD. WP = A0 = A1 = A2 = V_SS. Stop command issued.
3. VIN or VOUT = V_SS to V_DD. Does not apply to WP, A2-A0 pins.
4. This parameter is characterized but not tested.
5. The input pull-down circuit is strong (50KΩ) when the input voltage is below V_IL and weak (1MΩ) when the
input voltage is above V_IH.
