EVALUATION KIT AVAILABLE

MAX3080–MAX3089

Fail-Safe, High-Speed (10Mbps),

Slew-Rate-Limited RS-485/RS-422 Transceivers

General Description

Next Generation Device Features

The MAX3080–MAX3089 high-speed transceivers for

RS-485/RS-422 communication contain one driver and

one receiver. These devices feature fail-safe circuitry,

which guarantees a logic-high receiver output when the

receiver inputs are open or shorted. This means that

the receiver output will be a logic high if all transmitters

on a terminated bus are disabled (high impedance).

The MAX3080/MAX3081/MAX3082 feature reduced

slew-rate drivers that minimize EMI and reduce reflec-

tions caused by improperly terminated cables, allowing

error-free data transmission up to 115kbps. The

MAX3083/MAX3084/MAX3085 offer higher driver out-

put slew-rate limits, allowing transmit speeds up to

500kbps. The MAX3086/MAX3087/MAX3088’s driver

slew rates are not limited, making transmit speeds up

to 10Mbps possible. The MAX3089’s slew rate is

selectable between 115kbps, 500kbps, and 10Mbps

by driving a selector pin with a single three-state driver.

♦ For Fault-Tolerant Applications:

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

Unit Load, +3.3V RS-485 Transceiver

♦ For Low-Voltage Applications:

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

Transceiver in a SOT23 Package

♦ For Multiple Transceiver Applications:

MAX3030E–MAX3033E: 15kV ESD-Protected,

+3.3V, Quad, RS-422 Transmitters

MAX3040–MAX3045: 10kV ESD-Protected, Quad,

+5V, RS-485/RS-422 Transmitters

Applications

RS-422/RS-485 Communications

Level Translators

These transceivers typically draw 375µA of supply

current when unloaded, or when fully loaded with the

drivers disabled.

Transceivers for EMI-Sensitive Applications

Industrial-Control Local Area Networks

All devices have a 1/8-unit-load receiver input imped-

ance that allows up to 256 transceivers on the bus. The

MAX3082/MAX3085/MAX3088 are intended for half-

duplex communications, while the MAX3080/MAX3081/

MAX3083/MAX3084/MAX3086/MAX3087 are intended

for full-duplex communications. The MAX3089 is selec-

table between half-duplex and full-duplex operation. It

also features independently programmable receiver

and transmitter output phase via separate pins.
