4.3. Input and Output Characteristics for Non-I
The unidirectional Si86xx inputs and outputs are standard CMOS drivers/receivers. The nominal output impedance
of an isolator driver channel is approximately 50 , ±40%, which is a combination of the value of the on-chip series
termination resistor and channel resistance of the output driver FET. When driving loads where transmission line
effects will be a factor, output pins should be appropriately terminated with controlled impedance PCB traces.

1. VDDI and VDDO are the input and output power supplies. V
2. Powered (P) state is defined as 3.0 V < VDD < 5.5 V.
3. Unpowered (UP) state is defined as VDD = 0 V.
4. X = not applicable; H = Logic High; L = Logic Low.
5. Note that an I/O can power the die for a given side through an internal diode if its source has adequate current.
6. See "6.Ordering Guide" on page 26 for details. This is the selectable fail-safe operating mode (ordering option). Some

devices have default output state = H, and some have default output state = L, depending on the ordering part number
(OPN). For default high devices, the data channels have pull-ups on inputs/outputs. For default low devices, the data
channels have pull-downs on inputs/outputs.
