MAX3440E–MAX3444E

±15kV ESD-Protected, ±60V Fault-Protected,

10Mbps, Fail-Safe RS-485/J1708 Transceivers

General Description

Features

The MAX3440E–MAX3444E fault-protected RS-485 and

J1708 transceivers feature ±60V protection from signal

faults on communication bus lines. Each device contains

one differential line driver with three-state output and one

differential line receiver with three-state input. The 1/4-unit-

load receiver input impedance allows up to 128 transceiv-

ers on a single bus. The devices operate from a 5V supply

at data rates of up to 10Mbps. True fail-safe inputs guar-

antee a logic-high receiver output when the receiver inputs

are open, shorted, or connected to an idle data line.

● ±15kV ESD Protection

● ±60V Fault Protection

● Guaranteed 10Mbps Data Rate

(MAX3441E/MAX3443E)

● Hot Swappable for Telecom Applications

● True Fail-Safe Receiver Inputs

● Enhanced Slew-Rate-Limiting Facilitates

Error-Free Data Transmission

(MAX3440E/MAX3442E/MAX3444E)

Hot-swap circuitry eliminates false transitions on the data

bus during circuit initialization or connection to a live

backplane. Short-circuit current-limiting and thermal shut-

down circuitry protect the driver against excessive power

dissipation, and on-chip ±15kV ESD protection eliminates

costly external protection devices.

● Allow Up to 128 Transceivers on the Bus

● -7V to +12V Common-Mode Input Range

● Automotive Temperature Range (-40°C to +125°C)

● Industry-Standard Pinout

The MAX3440E–MAX3444E are available in 8-pin SO

and PDIP packages and are specified over industrial and

automotive temperature ranges.
