Notes:

1. 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.

2. tPSK(P-P) is the magnitude of the difference in propagation delay times measured between different units

operating at 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.
