2.3. Device Operation
Device behavior during start-up, normal operation, and shutdown is shown in Table 12. Table 13 provides an
overview of the output states when the Enable pins are active.

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. No Connect (NC) replaces EN1 on Si8440/45. No Connect replaces EN2 on the Si8445. No Connects are not internally
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. Note that an I/O can power the die for a given side through an internal diode if its source has adequate current.
8. When using the enable pin (EN) function, the output pin state is driven to a logic low state when the EN pin is disabled
