Description
The Si858x products are devices that bine robust, fully pliant RS-485 transceivers with signal isolation. These devices are ideal for industrial automation applications that require isolated interfaces for Field Bus systems that form a munication network for connecting sensors, actuators, and controllers.
These devices are ideal for isolating nodes on Field Buses based on the RS-485 standard, such as Profi Bus or Mod Bus. These transmission lines can be susceptible to electrical noise transients especially in harsh environments such as a factory floor, or in sensitive environments such as process control or data acquisition. Isolation provides a means of protection from such transients and noise that could corrupt signal integrity.
These isolated transceivers can operate with a 3.3 V or 5.0 V nominal power supply and have robust bus fault tolerance up-to ±30 V for protecting against harmful transients in noisy environment where such systems are often utilized. The bus pins are also protected up to 15 k V HBM ESD. Product options are available for half duplex and full duplex mode in industry standard footprints and incorporate slew rate controlled drivers with 1 Mbps data rate capability for reducing the EMI profile or options for high data rate up to 10 Mbps with no slew rate control implemented. These products also offer safety and protection features
