RS-485 is a robust communication interface that is commonly used  in harsh and noisy environments. There are many types of noise events that can happen on the RS-485 bus lines, but the most severe event is the IEC 61000-4-5 surge. In this video you will learn how our RS-485 transceivers are helping designers operate in rugged environments (such as a factory or the outdoors) while eliminating external system-protection components.
