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 Si84xx is
4. "Powered" state (P) is defined as 2.70 V < VDD < 5.5 V.
5. "Unpowered" state (UP) is defined as VDD = 0 V.
6. When using the enable pin (EN) function, the output pin state goes into a high-impedance state when the EN pin is
