MAX3098EBCSE

Overview

The MAX3098EBCSE+ 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 and IEC 1000-4-2 standards, alongside an extended common-mode input range from -10V to +13.2V. It detects open-circuit, short-circuit, low differential voltage, and common-mode violations. The part is housed in a 16-pin SO package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• Detects open-circuit, short-circuit, low differential voltage, and common-mode range violations
• Provides independent alarm outputs for each receiver channel plus a delayed general fault output
• Includes capacitor-programmable delay to prevent erroneous fault triggering at slow edge rates
• Features ±15kV ESD protection on all receiver inputs

Applications

• Motor-shaft encoder receivers
• High-speed triple RS-485/RS-422 receiver systems
• Telecommunications equipment
• Embedded systems requiring robust signal integrity monitoring

Procurement Notes

Verify the specific suffix 'BCSE' against official documentation to confirm the exact package type (SO) and commercial temperature range (0°C to +70°C). Ensure that any ordering suffixes do not alter functional parameters unless explicitly stated in the manufacturer's datasheet. Cross-reference the component status to confirm availability before finalizing procurement plans.

Selection Notes

Select this component when designing motor control feedback loops or industrial communication networks requiring high-speed differential signaling with built-in line fault monitoring. The MAX3098E variant specifically offers tighter differential fault thresholds compared to the MAX3097E, making it suitable for applications demanding precise detection of low-signal conditions without external threshold adjustments.

Part Context

The MAX3098EBCSE belongs to the MAX3097E/MAX3098E family of triple RS-422/RS-485 receivers designed for harsh industrial environments. While functionally similar to the MAX3097E, the MAX3098E features distinct fault-detection thresholds optimized for specific encoder signal integrity requirements. Both variants share the same pinout and core architecture but differ in their sensitivity settings for differential input faults.

Replacement Considerations

The MAX3097EBCSE serves as a direct pin-compatible alternative within the same family, differing primarily in fault-detection threshold specifications. Verify that the system can tolerate the MAX3097E's wider differential fault window if substituting for the MAX3098E.
