Notes:
N r 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
fo ^{where transmission line effects will be a factor, output pins should be appropriately terminated with controlled}
impedance PCB traces.
2. t_PSK(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.
