3 Summary

In this application note, some useful features in RS-485 transceivers like high fault voltage, wide common mode range, deglitch enable are discussed. The devices with these features like THVD24x0 can make the system much easier to design around. For example, high fault voltage and integrated IEC ESD protection can eliminate the need for external system-level protection components. Extended ±25-V input common-mode range greatly helps establish reliable data communication over longer cable run lengths and/or in the presence of large ground loop voltages. The deglitch feature at the enable pins make the device a great fit for noisy environment.
