MAX3097ECSE+

MAX3097ECSE+ is a ±15kV ESD-protected, 32Mbps, 3V/5V, triple RS-422/RS-485 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. The MAX3097E indicates when a receiver input is in an open-circuit condition, short-circuit condition, or outside the common-mode range. It also generates a fault indication when the differential input voltage goes below a preset threshold. It is used in applications such as RS-485/RS-422 receivers for motor-shaft encoders, high-speed, triple RS-485/RS-422 receivers with extended electrostatic discharge (ESD), triple RS-485/RS-422 receivers with input fault indication, telecommunications, embedded systems.
