Hot-Swappable Auto Polarity Reversal RS-485 Transceivers

Union Semiconductor

UM3487E Features

* 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 UM34

UM3487E General Description

The UM3487E series are +3.3V powered ±15kV ESD protected, fail-safe, hot-swappable, auto polarity reversal RS-485 transceivers. The device includes fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open, shorted or idle. This means that the receiver out.
