MAX3098EAEPE+

Overview

The MAX3098EAEPE+ is a triple RS-422/RS-485 receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +3V to +5.5V supply and supports data rates up to 32Mbps. The device features fault-detection circuitry with independent alarm outputs for each receiver and a delayed general fault output. It provides ±15kV ESD protection via Human Body Model and IEC 1000-4-2 standards. The component is housed in a 16-pin Plastic DIP package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Detects open-circuit, short-circuit, low differential voltage, and common-mode range violations
• Includes capacitor-programmable delay to prevent erroneous fault conditions at slow edge rates
• Provides independent universal fault outputs alongside standard receiver outputs

Applications

• Motor-shaft encoder receivers
• Telecommunications systems
• Embedded systems requiring high-speed serial communication

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and temperature rating. Confirm RoHS compliance status through current datasheets or distributor declarations before procurement. Ensure the supplier source is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when designing motor-control feedback systems that require robust fault detection for shaft encoders. It is suitable for applications needing extended common-mode ranges and high ESD immunity without external protection components. Compare against similar receivers if lower data rates or fewer channels are sufficient for the design requirements.

Part Context

This part belongs to the MAX3097E/MAX3098E series of high-speed RS-485/RS-422 receivers. It shares functional similarities with the MAX3097E but includes enhanced fault detection thresholds. The series is designed to replace industry-standard solutions like the 26LS31/32 while offering a smaller footprint and integrated diagnostic capabilities.

Replacement Considerations

Direct pin-compatible replacements include other parts from the MAX3097E/MAX3098E family, such as the MAX3097EAEPE+. Verify electrical characteristics and fault threshold specifications when substituting with non-family components.
