4 Summary

It is clear that most of the possible variability in the RS-485 design process can be handled by one RS-485 device – the THVD1424. Not only will this process also impact the difference between different application designs (with one only one-part design changes are typically marginal) but also has the potential to save on time spent qualifying devices – as a new device selection isn’t needed with each new RS-485 based application.
