Connecting Everyone and Everything, All the Time

Skyworks is pleased to introduce Si858x: Isolated RS-485 Transceivers.  

Si858x products combine robust fully compliant Rs-485 transceivers with Skyworks' Proprietary CMOS isolation technology. These devices are ideal for industrial applications that require isolated interfaces with a FieldBus system such as ProfiBus or ModBus, based on a RS-485 physical layer. The integrated isolation provides protection from high voltages and transient noise that could damage sensitive electronic components or corrupt signal integrity.  

Si858x: Isolated RS-485 Transceivers  

Features 

• Compliance to TIA/EIA-485-A (RS-485), conformance to EN 50170 (ProfiBus)
• Signaling rates of 1 Mbps (slew rate limited) or up to 10 Mbps
• Robust isolation: 5.0 kVRMS max isolation, working voltage of 2121 Vpeak
• Bus fault protection: ±30 V; HBM 15 kV bus pin ESD ratings
• Immunity to noise: 100 kV/µs Common Mode Transient Immunity (CMTI)
• Pin compatibility with standard industry footprint
• Flexibility with product options: 3.3 V or 5.0 V rated options, half and full duplex configurations available
