MAX3098EAEEE+

Overview

The MAX3098EAEEE+ is a triple RS-422/RS-485 receiver featuring integrated fault-detection circuitry and dedicated fault-status outputs. It operates on a single +3V to +5.5V supply with a maximum data rate of 32Mbps. The device provides ±15kV ESD protection via Human Body Model, IEC 1000-4-2 Air-Gap Discharge, and ±8kV Contact Discharge standards. It detects open-circuit conditions, short-circuit conditions, low differential voltage signals, and common-mode range violations. The part is housed in a 16-pin QSOP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Detects open-circuit, short-circuit, low differential voltage, and common-mode range violation faults
• Provides independent universal fault outputs and a capacitor-programmable delayed fault output
• Features ±15kV ESD protection for robust operation in harsh environments
• Supports extended common-mode input voltage range from -10V to +13.2V

Applications

• Motor-shaft encoders
• High-speed triple RS-485/RS-422 receivers with extended ESD protection
• Triple RS-485/RS-422 receivers with input fault indication
• Telecommunications systems
• Embedded systems

Procurement Notes

Verify the specific suffix EAEEE against official documentation to confirm the 16-pin QSOP package and industrial temperature range (-40°C to +85°C). Ensure compatibility with system requirements for triple-channel reception and fault detection logic. Cross-reference the manufacturer's ordering information to validate current production status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when designing motor control feedback loops requiring high-speed signal integrity and comprehensive fault monitoring. The MAX3098E is specifically optimized for absolute positioning control circuits where detecting encoder cable faults is critical. Compare its extended common-mode range and programmable delay features against standard receivers to ensure adequate noise immunity and error handling capabilities for the target application environment.

Part Context

The MAX3098E belongs to the MAX3097E/MAX3098E family of rugged, low-power RS-422/RS-485 receivers. These devices are engineered to replace industry-standard solutions while offering enhanced diagnostic capabilities. The family includes variants with different temperature ranges and packages, such as SO and Plastic DIP options, allowing designers to choose the form factor that best fits their PCB layout and environmental constraints.

Replacement Considerations

The MAX3097E is a pin-compatible alternative within the same family, differing primarily in fault-detection threshold specifications. Verify that the specific fault thresholds of the replacement part align with the system's sensitivity requirements before substitution.
