Note: 
            
- Single-Wire voltage (VPUP) must never be greater than the maximum VPUP operating voltage.
 - For the lowest system current, the SI/O signal must be driven to VPUP by the host or allowed to be pulled up by the pull-up resistors.
 - Input High leakage can not be measured because the device and decoupling capacitor is charged via the SI/O signal.
 - This condition is characterized but not production tested.
 - The Theta-JA for this package is applicable when the device is soldered to a board. Typically this package is not mounted this way.
