The ISO1042 possesses 7kV peak isolation voltage and has a typical transient immunity of 100kV/µs. The device operates from a 1.8V to 5V nominal supply on the primary side and a 5V nominal supply on the secondary side. This is of particular advantage for applications operating in harsh industrial environments.
The wide range of supply voltages on the primary side enables the connection to low-voltage microcontrollers for power preservation, whereas the 5V on the secondary side maintains a high signal-to-noise ratio of the bus signals.
