UM3483E/UM3486E

3V to 5.5V-Powered, ±15kV ESD-Protected,

Slew-Rate-Limited, True RS-485 Transceivers

UM3483E/UM3486E SOP8/DIP8

General Description

The UM3483E, UM3486E are 3V to 5.5V-powered, ±15kV ESD-protected, slew-rate-limited

differential transceivers which provide full RS485 compatibility. 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 which minimizes EMI and reduces

reflections resulted from improperly terminated cables. The UM3483E allows up to 500kbps

error-free data transmission, while the partially slew-rate-limited UM3486E transmits at data rates

up to 2.5Mbps.

The UM3483E, UM3486E also feature enhanced electrostatic discharge (ESD) protection. All of

the transmitter outputs and receiver inputs are protected to ±15kV using IEC61000-4-2 Air-Gap

Discharge, ±15kV using the Human Body Model and ±8kV using IEC61000-4-2 Contact

Discharge.

Drivers are short-circuit current limited. When the driver outputs are placed into a

high-impedance state by thermal shutdown circuitry, drivers are protected against excessive

power dissipation. And the fail-safe feature of the receiver input guarantees a logic-high output if

both inputs are open, shorted or idle.

Both parts have power up/down mode, the glitch-free driver outputs permit live insertion or

removal of the transceiver into/from the data bus. The CMOS design offers significant power

savings without sacrificing ruggedness against overload or ESD damage. The typical quiescent

current is only 300μA during operation and 1μA in shutdown mode.

The UM3483E, UM3486E are intended for half-duplex communication and are available in SOP8

and DIP8 packages.
