Notes:
1. The nominal output impedance of a non-I²C 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. 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.
