Notes:

VDDP current needed for dc-dc circuits.

4.

VDDA current needed for dc-dc circuits.

5.

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.

6.

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.

7.

Start-up time is the time period from when the UVLO threshold is exceeded to valid data at the output.
