Note:
1. VDD1 = 3.3 V ±10%; VDD2 = 3.3 V ±10%, TA = –40 to 125 °C
2. The nominal output impedance of an isolator driver channel is approximately 50 Ω, ±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.
3. 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.
4. Start-up time is the time period from the application of power to the appearance of valid data at the output.
