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. 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.
