Overview

UM3487E ±15kV ESD-Protected, Fail-Safe, Hot-Swappable Auto Polarity Reversal RS-485 Transceivers UM3487E SOP8/DIP8 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 output will be logic high if all transmitters on a terminated bus are disabled (high impedance).
The UM3487E features reduced slew-rate driver that minimizes EMI and reduces reflections caused by improperly terminated cables, allowing error-free data transmission up...
