High-ESD Profibus RS-485 Transceiver

General Description

Features

S Meets EIA 61158-2 Type 3 PROFIBUS-DP

The MAX14770E is a half-duplex, Q35kV high ESD-

protected transceiver for PROFIBUS-DP and RS-485

applications. In addition, it can be used for RS-422/V.11

communications. The MAX14770E is designed to meet

IEC 61158-2, TIA/EIA-422-B, TIA/EIA-485-A, V.11, and

X.27 standards.

S +4.5V to +5.5V Supply Voltage

S 20Mbps Data Rate

S Short-Circuit Protected

S True Fail-Safe Receiver

S Thermal-Shutdown Protected

S Hot Swappable

The MAX14770E operates from a +5V supply and has

true fail-safe circuitry that guarantees a logic-high receiv-

er output when the receiver inputs are open or shorted.

S High ESD Protection

The MAX14770E features a 1/4 standard-unit load

receiver input impedance, allowing up to 128 1/4 unit

load transceivers on the bus. Drivers are short-circuit

current limited and are protected against excessive

power dissipation by thermal-shutdown circuitry.

S -40NC to +125NC Automotive Temperature Range

The MAX14770E is available in 8-pin SO and tiny TDFN

(3mm x 3mm) packages, and is specified over the extend-

ed (-40NC to +85NC) and automotive (-40NC to +125NC)

temperature ranges.
