General Description

The Si858x products are devices that combine robust, fully compliant RS-485 transceivers with signal  isolation.

These devices are ideal for industrial  automation applications that require isolated  interfaces for FieldBus systems that form a  communication network for connecting sensors,  actuators, and controllers.

These devices are ideal for isolating nodes on FieldBuses based on the RS-485 standard, such as  ProfiBus or ModBus.

Key Features

  • Compliance to TIA/EIA-485-A (RS-485), compatible with EN 50170 (ProfiBus).
  • Industry standard footprint and logic operation.
  • Signaling rates of up to 10 Mbps.
  • HBM 15 kV bus pin ESD ratings.
  • Common mode voltage supported for operation: .
  • 7 V to +12 V.
  • Bus fault protection: ±30 V.
  • Thermal shutdown protection.
  • VDD1: 3.0 V to 5.5 V.
  • VDD2: 3.3 V or 5.0 V options.
  • 17 ns typical driver propagation delay.
