MAX3097EEEE+T

This product features three high-speed RS-485/RS-422 receivers with fault detection circuitry and fault status outputs. The receiver inputs incorporate fault thresholds to detect when a component is in an invalid state, and can indicate whether the receiver inputs are open-circuited, short-circuited, or outside the common-mode range. A fault indication is also generated when the differential input voltage falls below a preset threshold. The fault circuitry includes a capacitor-programmable delay to ensure that no false fault conditions occur even at slow edge rates. Each receiver is capable of receiving data at rates up to 32Mbps.

Applications

• RS-485/RS-422 motor shaft encoder receiver
• High-speed, triple RS-485/RS-422 receiver with extended ESD protection
• Triple RS-485/RS-422 receiver with input fault indication
• Telecommunications
• Embedded systems

Key features

• Detects the following RS-485 faults: open-circuit, short-circuit, low differential voltage signal, common-mode range violation
• ESD protection:
• ±15kV — Human Body Model
• ±15kV — IEC 1000-4-2, air-gap discharge
• ±8kV — IEC 1000-4-2, contact discharge
• Single +3V to +5.5V operation
• -10V to +13.2V extended common-mode range
• Capacitor-programmable fault indication delay for error-free operation at low data rates
• Individual and combined fault outputs
• 32Mbps data rate
• 16-pin QSOP — 40% smaller than industry-standard 26LS31/32 solutions
