±±15k EꢀDꢁ-rotected, 32Mbps, 3k/1k,

Triple Rꢀꢁ422/Rꢀꢁ481 Receivers with Fault Detection

General Description

Features

The MAX3097E/MAX3098E feature three high-speed RS-

485/RS-422 receivers with fault-detection circuitry and

fault-status outputs. The receivers’ inputs have fault

thresholds that detect when the part is not in a valid state.

ꢀ Detects the Following RS-485 Faults:

Open-Circuit Condition

Short-Circuit Condition

Low Differential Voltage Signal

Common-Mode Range Violation

The MAX3097E/MAX3098E indicate when a receiver

input is in an open-circuit condition, short-circuit condi-

tion, or outside the common-mode range. They also

generate a fault indication when the differential input

voltage goes below a preset threshold. See Ordering

Information or the Electrical Characteristics for thresh-

old values.

The fault circuitry includes a capacitor-programmable

delay to ensure that there are no erroneous fault condi-

tions even at slow edge rates. Each receiver is capable

of accepting data at rates up to 32Mbps.
