±15kV ESD-Protected, Fail-Safe, High-Speed (10Mbps),

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

MAX3080E–MAX3089E

General Description

The MAX3080E–MAX3089E are ±15kV electrostatic dis-

charge (ESD)-protected, high-speed transceivers for RS-

485/RS-422 communication that 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

MAX3080E/MAX3081E/MAX3082E 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

MAX3083E/MAX3084E/MAX3085E offer higher driver

output slew-rate limits, allowing transmit speeds up to

500kbps. The MAX3086E/MAX3087E/ MAX3088Es’ dri-

ver slew rates are not limited, making transmit speeds

up to 10Mbps possible. The MAX3089E’s slew rate is

selectable between 115kbps, 500kbps, and 10Mbps by

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

devices feature enhanced ESD protection. All transmitter

outputs and receiver inputs are protected to ±15kV

using the Human Body Model.

These transceivers typically draw 375µA of supply

current when unloaded, or when fully loaded with the dri-

vers disabled.

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

that allows up to 256 transceivers on the bus. The

MAX3082E/MAX3085E/MAX3088E are intended for half-

duplex communications, while the MAX3080E/MAX3081E/

MAX3083E/MAX3084E/MAX3086E/MAX3087E are

intended for full-duplex communications. The MAX3089E

is selectable between half-duplex and full-duplex opera-

tion. It also features independently programmable

receiver and transmitter output phase via separate pins.
