Overview

UM3352E ±15kV ESD-Protected, Slew-Rate-Limited, Fail-Safe, True RS-485 Transceivers UM3352E SOP8/DIP8 General Description The UM3352E series are ±15kV ESD-protected, high-speed, half-duplex transceivers for RS-485 communication that contain one driver and one receiver.
The device features 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 UM3352E features reduced slew-rate driver that minimizes EMI and reduces reflections caused by improperly terminated cables, allowing error-free data transmission up to 500kbps.
It also features enhanced ESD protection.
All transmitter outputs and receiver inputs incorporate advanced structures allowing them to survive ESD events in excess of ±15kV Human Body Mode and IEC61000-4-2 Air Discharge Mode, ±8kV IEC61000-4-2 Contact Discharge Mode.
