3.3. Input and Output Characteristics for Non-I
The Si84xx inputs and outputs for unidirectional channels are standard CMOS drivers/receivers. The nominal
output impedance of an isolator driver channel is approximately 85 , ±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. Table 12 details powered and unpowered operation of the Si84xx’s non-I

1. VDDI and VDDO are the input and output power supplies. V
2. X = not applicable; H = Logic High; L = Logic Low.
3. Powered (P) state is defined as 3.0 V < VDD < 5.5 V.
4. Unpowered (UP) state is defined as VDD = 0 V.
5. Note that an I/O can power the die for a given side through an internal diode if its source has adequate current.
