UM3087E Datasheet (Union Semiconductor) - Hot-Swappable Auto Polarity Reversal RS-485 Transceivers

UM3087E, Hot-Swappable Auto Polarity Reversal RS-485 Transceivers

The UM3087E series are +5.0V 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 outp
