Each bit must be limited to a maximum of 25 mA and the total package limited to 100 mA due to internal busing limits.
Minimum SCL clock frequency is limited by the bus time-out feature, which resets the serial bus interface if either SDA or SCL is held
LOW for a minimum of 25 ms. Disable bus time-out feature for DC operation.
