MAX13450E/MAX13451E

RS-485 Transceivers with Integrated

100Ω/120Ω Termination Resistors

General Description

Beneﬁts and Features

● Easy Configuration of RS-422 and RS-485 Networks

The MAX13450E/MAX13451E are half-duplex and full-

duplex RS-485/RS-422 transceivers. These devices fea-

ture internal 100I and 120I termination resistors. The

resistor values are pin selectable. A logic supply input

allows interfacing to logic levels down to +1.8V.

Up to 20Mbps (max) Data Rate

•ꢀ Software/Pin-Selectableꢀ100Ω/120ΩꢀTermination

•ꢀ Integrated, Switchable Resistors Eliminate the

Need for External Resistors or DIP Switches

•ꢀ DriverꢀDrivesꢀ100ΩꢀDoubleꢀTerminationꢀandꢀ

Supports Cat-5/Cat-6 and 24-AWG Cables

•ꢀ Pin-Selectable Slew-Rate Limiting Reduces EMI

for Data Rates Up to 500kbps

The MAX13450E/MAX13451E feature strong drivers

specified to drive low-impedance lines found when a

fully loaded bus, based on today’s 100I characteristic

impedance cable, is doubly terminated. Both devices

allow slew-rate limiting of the driver output to reduce EMI

and reflections for data rates up to 500kbps.

● Designed to Perform in Harsh Environments

•ꢀ Extended ESD Protection

The MAX13451E has a FAULT alarm indication output to

signal to the system that an error condition exists in the

driver. The MAX13451E also features a logic inversion

function. The logic inversion allows phase reversal of the

A-B signals in case these are inadvertently connected

wrongly.

±30kV Human Body Model

±15kV Air Gap Discharge per IEC 61000-4-2

±7kV Contact Discharge per IEC 61000-4-2

•ꢀ Inverting of A, B Line Polarity (MAX13451E) Allows

Phase Reversal if Misconnected

The MAX13450E/MAX13451E have 1/8-unit load receiver

input impedance, allowing up to 256 transceivers on the

bus. All driver outputs are protected to Q30kV ESD using

the Human Body Model (HBM).

•ꢀ +4.5V to +5.5V Supply Voltage Range

The MAX13450E/MAX13451E are available in a 14-pin

TSSOP package and operate over the automotive -40NC

to +125NC temperature range.
