Half-Duplex RS-485-/RS-422-Compatible

Transceiver with AutoDirection Control

General Description

Features

The MAX13487E/MAX13488E +5V, half-duplex, 15ꢀV

ESD-protected RS-485/RS-422-compatible transceivers

feature one driver and one receiver. The MAX13487E/

MAX13488E include a hot-swap capability to eliminate

false transitions on the bus during power-up or live

insertion.

♦ +5V Operation

♦ AutoDirection Enables Driver Automatically on

Transmission

♦ Hot-Swappable for Telecom Applications

♦ Enhanced Slew-Rate Limiting Facilitates Error-

Free Data Transmission (MAX13487E)

♦ High-Speed Version (MAX13488E) Allows for

Transmission Speeds Up to 16Mbps

♦ Extended ESD Protection for RS-485 I/O Pins

15ꢀV Human ꢁody Model

The MAX13487E/MAX13488E feature Maxim’s propri-

etary AutoDirection control. This architecture maꢀes the

devices ideal for applications, such as isolated RS-485

ports, where the driver input is used in conjunction with

the driver-enable signal to drive the differential bus.

♦ 1/4-Unit Load, Allowing Up to 128 Transceivers on

the ꢁus

The MAX13487E features reduced slew-rate drivers

that minimize EMI and reduce reflections caused by

improperly terminated cables, allowing error-free trans-

mission up to 500ꢀbps. The MAX13488E driver slew

rate is not limited, allowing transmit speeds up to

16Mbps.

♦ 8-Pin SO Pacꢀage

Ordering Information/

Selector Guide

The MAX13487E/MAX13488E feature a 1/4-unit load

receiver input impedance, allowing up to 128 trans-

ceivers on the bus. These devices are intended for half-

duplex communications. All driver outputs are

protected to 15ꢀV ESD using the ꢁuman ꢂody Model.

The MAX13487E/MAX13488E are available in an 8-pin

SO pacꢀage. The devices operate over the extended

-40°C to +85°C temperature range.
