Datasheet	UM3089E-UnionSemiconductor.pdf

The UM3089E series are +5.0V-powered, ±15kV ESD protected, fail-safe, hot-swappable, auto polarity reversal RS-485 transceivers.

reduced slew-rate driver that minimizes EMI and reduces reflections caused by improperly terminated cables, allowing error-free data transmission up to 500kbps. All transmitter outputs and receiver inputs are protected to ±15kV using the Human Body Model and IEC61000-4-2, Air-Gap Discharge. The UM3089E includes cable auto-invert functions that reverse the polarity of the RS485 bus pins in case the cable is misconnected. Receiver’s full fail-sa.
