2 Design Considerations

Prevents DC and unwanted AC currents between controller devices and peripheral ICs
Allows signal transfer between controller devices and peripheral ICs
Protects low voltage parts in a system from high voltage circuits
Diminishes the effect of ground potential difference
[FAQ] Why is the logic LOW level output voltage, VOL1, up to 0.8 V on Side 1 of the ISO1540/ISO1541 and ISO1640/ISO1641 bidirectional I2C isolators?
