Notes:

1. The nominal output impedance of an isolator driver channel is approximately 50 ï, Â±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.
