What are the key features of ISO3080DWG4?
- 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
What is ISO3080DWG4 used for?
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.
