Notes:
1. Specifications in this table are also valid at VDD1 = 2.6 V and VDD2 = 2.6 V when the operating temperature range is
constrained to T_A = 0 to 85 °C.
2. The nominal output impedance of an 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.
3. 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.
4. Start-up time is the time period from the application of power to valid data at the output.
