The LTC2876 and LTC2877 are designed to be true PROFIBUS compatible transceivers, tested using PROFIBUS loads and defined per exact specifications from PROFIBUS IEC 61158-2. Similarly, the LTC2876 and LTC2877 can also be used in 5V or low power, low swing 3V RS485 applications, since they also have been tested using RS485 loads and defined per exact specifications from TIA/EAI-485-A. The circuit shown exemplifies just one of many interesting types of PROFIBUS applications. Here, the LTM2892 6-channel digital isolator galvanically isolates the LTC2876 and the PROFIBUS bus from the rest of the system, breaking any ground loops that may have existed.
