* 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 VDD-0.3V and VSS, other inputs VSS or VDD-0.3V
2.
SCL = SDA = VDD. All inputs VSS or VDD. Stop command issued.
3.
VIN or VOUT = VSS to VDD. Does not apply to WP, A2-A0 pins.
4.
This parameter is characterized but not tested.
5.
The input pull-down circuit is strong (20K
Ω) when the input voltage is below V
IL and weak (1MΩ) when the input voltage
is above VIH. This resistance is characterized and not tested.
