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 , such as...
