EMC protected, 500-Kbps, full-duplex, 5-kVrms isolated RS-485 & RS-422 transceiver

The ISO14xx devices are

galvanically-isolated differential line transceivers for TIA/EIA RS-485 and RS-422

applications. 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 (see Reinforced and Basic Isolation Options).
