RS-422 Transceivers

5–MAX3469

General Description

Features

♦ Recommended for Profibus Applications

The MAX3465–MAX3469 are high-speed differential

bus transceivers for RS-485 and RS-422 communica-

tions. They are designed to meet TIA/EIA-422-B,

TIA/EIA-485-A, V.11, and X.27 standards. The trans-

ceiver complies with the Profibus specification provid-

ing +2.1V minimum output level with a 54Ω load,

40Mbps data rate, and output skew less than 2ns. Each

part contains one three-state differential line driver and

one differential input line receiver. The devices operate

from a +5V supply and feature true fail-safe circuitry,

which guarantees a logic-high receiver output when the

receiver inputs are open or shorted. This enables all

receiver outputs on a terminated bus to output logic

highs when all transmitters are disabled.

♦ Up to 40Mbps Data Rate

♦ 15ns Transmitter Propagation Delay

♦ 20ns Receiver Propagation Delay

♦ 2ns Transmitter and Receiver Skew

♦ High Differential Driver Output Level (2.1V on 54Ω)

♦ Hot-Swap Versions

♦ 1µA Shutdown Supply Current

♦ Low Supply Current Requirements (2.5mA, typ)

♦ Allow Up to 128 Transceivers on the Bus

All devices feature a 1/4-standard-unit load receiver

input impedance that allows 128 transceivers on the

bus. Driver and receiver propagation delays are guar-

anteed under 20ns for multidrop, clock distribution

applications. Drivers are short-circuit current limited

and are protected against excessive power dissipation

by thermal-shutdown circuitry. The driver and receiver

feature active-high and active-low enables, respective-

ly, that can be connected together externally to serve

as a direction control.

♦ True Fail-Safe Receiver while Maintaining EIA/TIA-

485 Compatibility

♦ Designed for Multipoint Transmissions on Long

or Noisy Bus Lines

♦ Full-Duplex and Half-Duplex Versions Available

♦ Phase Controls to Correct for Twisted-Pair

Reversal for 14-Pin Versions

♦ Current-Limiting and Thermal Shutdown for

Driver Overload Protection
