MAX3098EBCSE+

MAX3098EBCSE+ ±15kV ESD-protected, 32Mbps, 3V/5V, triple receiver with fault detection. It features 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. It indicates 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. 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. Applications include RS-485/RS-422 receivers for motor-shaft encoders, high-speed, triple RS-485/RS-422 receiver with extended electrostatic discharge (ESD), triple RS-485/RS-422 receiver with input fault indication, telecommunications, and embedded systems.
