Low-Power, Slew-Rate-Limited

RS-485/RS-422 Transceivers

General Description

__Next Generation Device Features

♦ For Fault-Tolerant Applications

The MAX481, MAX483, MAX485, MAX487–MAX491, and

MAX1487 are low-power transceivers for RS-485 and RS-

422 communication. Each part contains one driver and one

receiver. The MAX483, MAX487, MAX488, and MAX489

feature reduced slew-rate drivers that minimize EMI and

reduce reflections caused by improperly terminated cables,

thus allowing error-free data transmission up to 250kbps.

The driver slew rates of the MAX481, MAX485, MAX490,

MAX491, and MAX1487 are not limited, allowing them to

transmit up to 2.5Mbps.

MAX3430: ±80V Fault-Protected, Fail-Safe, 1/4

Unit Load, +3.3V, RS-485 Transceiver

MAX3440E–MAX3444E: ±15kV ESD-Protected,

±60V Fault-Protected, 10Mbps, Fail-Safe,

RS-485/J1708 Transceivers

♦ For Space-Constrained Applications

MAX3460–MAX3464: +5V, Fail-Safe, 20Mbps,

Profibus RS-485/RS-422 Transceivers

MAX3362: +3.3V, High-Speed, RS-485/RS-422

Transceiver in a SOT23 Package

These transceivers draw between 120µA and 500µA of

supply current when unloaded or fully loaded with disabled

drivers. Additionally, the MAX481, MAX483, and MAX487

have a low-current shutdown mode in which they consume

only 0.1µA. All parts operate from a single 5V supply.

MAX3280E–MAX3284E: ±15kV ESD-Protected,

52Mbps, +3V to +5.5V, SOT23, RS-485/RS-422,

True Fail-Safe Receivers

MAX3293/MAX3294/MAX3295: 20Mbps, +3.3V,

SOT23, RS-855/RS-422 Transmitters

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-imped-

ance state. The receiver input has a fail-safe feature that

guarantees a logic-high output if the input is open circuit.

♦ For Multiple Transceiver Applications

MAX3030E–MAX3033E: ±15kV ESD-Protected,

+3.3V, Quad RS-422 Transmitters

The MAX487 and MAX1487 feature quarter-unit-load

receiver input impedance, allowing up to 128 MAX487/

MAX1487 transceivers on the bus. Full-duplex communi-

cations are obtained using the MAX488–MAX491, while

the MAX481, MAX483, MAX485, MAX487, and MAX1487

are designed for half-duplex applications.

♦ For Fail-Safe Applications

MAX3080–MAX3089: Fail-Safe, High-Speed

(10Mbps), Slew-Rate-Limited RS-485/RS-422

Transceivers

♦ For Low-Voltage Applications
