ISO1430DW developed by Microchip Technology is a type of galvanically-isolated differential line transceiver with robust EMC, which is available for both basic and reinforced isolation. It is specifically designed for TIA/EIA RS-485 and RS-422 applications, as well as harsh industrial environments. With the bus pins, high levels of IEC electrostatic discharge (ESD) and IEC electrical fast transient (EFT) events can be ensured, thus eliminating the need for additional components on bus for system-level protection.
