3 Description

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).
