UM3483E, UM3486E

3.3V-Powered, ±±15V ESD-Protected,

and Slew-Rate-Limited True RS-481 Transceivers

General Description

The UM3483E, UM3486E are +15 KV ESD protected, slew-rate limited, ultra lower differential line transceivers which provide full

RS485 compatibility while operating from single 3.3V supply. Each part contains one driver and one receiver, which is designed for

data transmission with extended common mode range (-7V to 12V). The UM3483E features slew-rate limited driver that minimizes

EMI and reduces reflections caused by improperly terminated cables, allowing error-free data transmission at data rate up to 500kbps,

while partially slew-rate limited UM3486E transmits up to 2.5Mbps.

All devices feature enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver inputs are protected to

15kV using IEC 1000-4-2 Air-Gap Discharge and 15kV using the Human Body Model.

Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that

places the driver outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if

both inputs are open, shorted or idle.

Both parts have power up/down glitch free driver outputs permit live insertion or removal of transceiver from/to data bus. The

CMOS design offers significant power savings without sacrificing ruggedness against overload or ESD damage. Typical quiescent

current is only 500 μA while operating and 1 μA in shutdown.

The UM3483E, UM3486E are fully specified over the commercial an extended industrial temperature range and are available in 8-pin

and DIP packages.
