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. See "3. Errata and Design Migration Guidelines" on page 25 for more details.

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