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.
