The MAX3097E/MAX3098E are three-channel 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 condition, 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 threshold values. The fault circuitry includes a capacitor-programmable delay to ensure that there are no erroneous fault conditions even at slow edge rates. Each receiver is capable of accepting data at rates up to 32Mbps.
The MAX3097E and MAX3098E are high‑speed, triple RS‑422/RS‑485 receivers designed for motor‑shaft encoders and other applications requiring robust fault detection. Each receiver provides independent fault‑status outputs for open‑circuit, short‑circuit, low differential voltage, and common‑mode range violations, with a programmable delay to avoid false alarms at slow edge rates.
The devices operate from a 3 V to 5.5 V supply, support data rates up to 32 Mbps, and feature +15 kV ESD protection (Human Body Model and IEC 1000‑4‑2 standards). They are offered in a 16‑pin QSOP package and include detailed pin descriptions, electrical characteristics, and typical operating curves.
