MikroElektronika 5kVRMS isolated half-duplex RS-485 transceiver from Texas Instruments ISO1450 RF Transceiver

The MikroElektronika Transceiver With Robust EMC devices are galvanically-isolated differential line transceivers. These noise-immune transceivers are designed to operate in harsh industrial environments. The bus pins of these devices can endure high levels of IEC electrostatic discharge (ESD) and IEC electrical fast transient (EFT) events which eliminates the need for additional components on bus for system-level protection. The devices are available for both basic and reinforced isolation.
