Key Features
- Galvanic isolation between bus and logic sides protects sensitive control circuitry from high-voltage transients on RS-485/RS-422 lines
- Differential Schmitt trigger receiver inputs deliver superior noise rejection for reliable communication over long cable runs in industrial environments
- Supports both EIA-485 (TIA-485) and EIA-422 (TIA-422) standards in a single 16-pin SOIC package for design flexibility
Applications
The ISO3080DWG4 is used in industrial automation networks, building control systems, and process control fieldbus links where galvanic isolation between the RS-485 bus and control logic is required to prevent ground loops and protect against high-voltage transients. It enables reliable half-duplex or full-duplex differential serial communication over cable distances of up to 1200 meters. It is also commonly used in motor drive interfaces, PLC communications, and isolated sensor bus applications.
