MAX3070E–MAX3079E

+3.3V, ±15kV ESD-Protected, Fail-Safe,

Hot-Swap, RS-485/RS-422 Transceivers

General Description

Beneﬁts and Features

The MAX3070E–MAX3079E 3.3V, ±15kV ESD-protected,

RS-485/RS-422 transceivers feature one driver and one

receiver. These devices include fail-safe circuitry, guaranteeing

a logic-high receiver output when receiver inputs are open

or shorted. The receiver outputs a logic-high if all transmitters

on a terminated bus are disabled (high impedance). The

devices include a hot-swap capability to eliminate false

transitions on the bus during power-up or hot insertion.

● Protection for Robust Performance

• ±15kV Human Body Model ESD on I/O Pins

• True Fail-Safe Receiver While Maintaining

EIA/TIA-485 Compatibility

• Enhanced Slew-Rate-Limiting Facilitates Error-

Free Data Transmission (MAX3070E-MAX3075E/

MAX3079E)

• Hot-Swap Input Structure on DE and RE

● Flexible Feature Set for Ease of Design

• Pin-Selectable Full/Half-Duplex Operation

(MAX3079E)

The MAX3070E/MAX3071E/MAX3072E feature reduced

slew-rate drivers that minimize EMI and reduce reflections

caused by improperly terminated cables, allowing error-

free data transmission up to 250kbps. The MAX3073E/

MAX3074E/MAX3075E also feature slew-rate-limited

drivers but allow transmit speeds up to 500kbps. The

MAX3076E/MAX3077E/MAX3078E driver slew rates are

not limited, making transmit speeds up to 16Mbps possible.

The MAX3079E slew rate is pin-selectable for 250kbps,

500kbps, and 16Mbps.

• Phase Controls to Correct for Twisted-Pair

Reversal (MAX3079E)

• Allows up to 256 Transceivers on the Bus

• Available in Industry-Standard SO and DIP packages

● 10µA Shutdown Current Mode for Power Savings

(Except MAX3071E/MAX3074E/MAX3077E)

Ordering Information at end of data sheet.

The MAX3072E/MAX3075E/MAX3078E are intended

for half-duplex communications, and the MAX3070E/

MAX3071E/MAX3073E/MAX3074E/MAX3076E/

MAX3077E are intended for full-duplex communications.

The MAX3079E is selectable for half-duplex or full-duplex

operation. It also features independently programmable

receiver and transmitter output phase through separate

pins.

Selector Guide, Pin Configurations, and Typical Operating

Circuits appear at end of data sheet.

The MAX3070E–MAX3079E transceivers draw 800μA

of supply current when unloaded, or when fully loaded

with the drivers disabled. All devices have a 1/8-unit load

receiver input impedance, allowing up to 256 transceivers

on the bus.

Applications

● Lighting Systems

● Industrial Control

● Telecom

● Security Systems

● Instrumentation
