MAX3098E

±15kV ESD-Protected, 32Mbps, 3V/5V,Triple RS-422/RS-485 Receivers with Fault Detection


Please check latest availability status for a specific part variant.

Description

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 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 in the full data sheet 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.
