ISO1450DWR

The ISO1450DWR isolation interface IC is a high-performance solution with broad compatibility and excellent features. It is compatible with TIA/EIA-485-A and PROFIBUS standards and provides powerful circuit protection functions, including electrostatic breakdown and electrical fast transient immunity protection. At the same time, it supports multiple data rates with low EMI and is suitable for different power supply conditions. Features fail-safe receiver to detect bus faults. High common-mode rejection ensures stable communication in noisy environments, while a wide operating temperature range and hot-swappable capabilities accommodate various environments. Package compatibility makes design and replacement easy for engineers.

The ISO1450 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).
