ISO14xx Isolated Transceivers

Texas Instruments ISO14xx Isolated Transceivers 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, eliminating the need for additional components on the bus for system-level protection. The devices are available for both basic and reinforced isolation.
