Renesas has three full featured RS-485 families that are recommended for new designs. All of the families feature high ESD, full failsafe and fractional unit load receivers, hot plug functions, half and full duplex options, tiny MSOP packages, and driver slew rate settings for slow, medium, and fast data rates. As mentioned on the previous slide, both the ISL315XE and ISL317XE are specified for IEC61000 ESD. The ISL315XE family features an exceptionally large differential output voltage that is 40% larger than required by the RS-485 standard. This feature allows the ISL315XE family to be utilized in PROFIBUS applications, and also provides more noise immunity than devices just meeting the minimum RS-485 requirement. For applications that require the most rugged transceivers, Renesas offers the fault protected and wide common mode range ISL3249XE family. One of its target applications is networks where the DC power supply cable is routed in the same conduit as the data cable. If a fault occurs where a 24V power line comes in contact with one of the RS-485 data lines, a standard -7V to +12V transceiver pin will be destroyed. The ±60V fault protection levels of this new family withstand these types of faults with plenty of margin. Likewise, the ±25V common mode range of the ISL3249XE family keeps the transceiver operating properly even with large ground potential differences that can occur between nodes communicating over long distances. Note that this family is specified for only HBM ESD levels, but this is in line with almost all of the competitive devices in the fault protected space.
