Notes:
1. The nominal output impedance of an isolator driver channel is approximately 85 , ±40%, which is a combination of the
o ^N _{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
N ^r _{impedance PCB traces.}
fo 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.
