Skyworks introduce Si858x: Isolated RS-485 Transceivers

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.
