Devices in the MAX3483E family (MAX3483E/MAX3485E/

MAX3486E/MAX3488E/MAX3490E/MAX3491E) a re

±15kV ESD-protected, +3.3V, low-power transceivers for

RS-485 and RS-422 communications. Each device con-

tains one driver and one receiver. The MAX3483E and

MAX3488E feature slew-rate-limited drivers that minimize

EMI and reduce reflections caused by improperly termi-

nated cables, allowing error-free data transmission at

data rates up to 250kbps. The partially slew-rate-limited

MAX3486E transmits up to 2.5Mbps. The MAX3485E,

MAX3490E, and MAX3491E transmit at up to 12Mbps.

♦ ESD Protection for RS-485 I/O Pins

±15kV—Human Body Model

±8kV—IEC 1000-4-2, Contact Discharge

±15kV—IEC 1000-4-2, Air-Gap Discharge

♦ Operate from a Single +3.3V Supply—

No Charge Pump Required

♦ Interoperable with +5V Logic

♦ Guaranteed 12Mbps Data Rate

(MAX3485E/MAX3490E/MAX3491E)

All devices feature enhanced electrostatic discharge

(ESD) protection. All transmitter outputs and receiver

inputs are protected to ±15kV using IEC 1000-4-2 Air-

Ga p Dis c ha rg e , ± 8kV us ing IEC 1000-4-2 Conta c t

Discharge, and ±15kV using the Human Body Model.

♦ Slew-Rate Limited for Errorless Data Transmission

(MAX3483E/MAX3488E)

♦ 2nA Low-Current Shutdown Mode

(MAX3483E/MAX3485E/MAX3486E/MAX3491E)

Drivers are short-circuit current limited and are protect-

ed 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

fe a ture tha t g ua ra nte e s a log ic -hig h outp ut if b oth

inputs are open circuit.

♦ -7V to +12V Common-Mode Input Voltage Range

♦ Full-Duplex and Half-Duplex Versions Available

♦ Industry-Standard 75176 Pinout

(MAX3483E/MAX3485E/MAX3486E)

♦ Current-Limiting and Thermal Shutdown for

The MAX3488E, MAX3490E, and MAX3491E feature

full-d up le x c ommunic a tion, while the MAX3483E,

MAX3485E, a nd MAX3486E a re d e s ig ne d for ha lf-
