Note:

All specifications not shown can be found in the All I/O Interfaces Table 3-1.
Single-Wire voltage (V_PUP) must never be greater than the maximum V_PUP operating voltage.
For the lowest system current, the SI/O signal must be driven to V_PUP by the host or allowed to be pulled up by the pull-up resistors.
Input High leakage cannot be measured in parasitic power mode because the device and decoupling capacitor are charged via the SI/O signal. Low leakage is valid provided device was charged to be within the operational range.
Operation over the C_BUS range is ensured by design and is not production tested.
