UM3352E

±12kV ESD-Protected, Slew-Rate-Limited, Fail-Safe, True

RS-485 Transceivers

UM3352E SOP8/DIP8

General Description

The UM3352E series are ±12kV ESD-protected, high-speed 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 are protected to ±12kV using IEC61000-4-2, Air-Gap Discharge.

The transceivers typically draw 400μA of supply current when unloaded, or when fully loaded

with the drivers disabled. The device has a 1/8-unit-load receiver input impedance that allows up

to 256 transceivers on the bus and are intended for half-duplex communications.
