Notes:

1. 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.

the same supply voltages, load, and ambient temperature.

3. Start-up time is the time period from the application of power to valid data at the output.
