6. The device is in standby mode after an I2C stop command.

7. The power−on reset circuit resets the I2C bus logic with VDD < VPOR and set all I/Os to logic 1 upon power−up. Thereafter, VDD must

be lower than 0.2 V to reset the part.

8. Each bit must be limited to a maximum of 25 mA and the total package limited to 400 mA due to internal busing limits.

9. The value is not tested, but verified on sampling basis.
