Isolated RS-485 Transceivers: Si858x
Source: Skyworks Solutions, Inc.

The 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 an 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.
