+5V, Fail-Safe, 20Mbps, Profibus RS-485/

RS-422 Transceivers

General Description

Features

ꢀ Recommended for Profibus Applications

The MAX3460–MAX3464 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 output level with a 54Ω load, 20Mbps data

rate, and output skew less than 2ns. Each part contains

one three-state differential line driver and one differen-

tial input line receiver. The devices operate from a +5V

supply and feature true fail-safe circuitry, which guaran-

tees 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.

ꢀ Guaranteed 20Mbps Data Rate

ꢀ 20ns Transmitter and 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

ꢀ True Fail-Safe Receiver while Maintaining EIA/TIA-

485 Compatibility

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.

ꢀ 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
