1. VDDI and VDDO are the input and output power supplies. V
2. X = not applicable; H = Logic High; L = Logic Low; Hi-Z = High Impedance.
3. It is recommended that the enable inputs be connected to an external logic high or low level when the Si845x is
4. No Connect (NC) replaces EN1 on Si8450. No Connects are not internally connected and can be left floating, tied to
5. "Powered" state (P) is defined as 2.70 V < VDD < 5.5 V.
6. "Unpowered" state (UP) is defined as VDD = 0 V.
7. When using the enable pin (EN) function, the output pin state is driven to a logic low state when the EN pin is disabled
