MAX3098EACPE

Overview

The MAX3098EACPE is a triple RS-422/RS-485 receiver featuring integrated fault-detection circuitry and dedicated fault-status outputs. It operates from a single +3V to +5.5V supply and supports data rates up to 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-circuits, low differential voltage signals, and common-mode range violations. The part includes a capacitor-programmable delay for the ALARMD output to prevent erroneous alarms during slow edge rates. It is housed in a 16-pin Plastic DIP package with an operating temperature range of 0°C to +70°C.

Feature Summary

• Detects open-circuit, short-circuit, low differential voltage, and common-mode range violation faults
• Provides independent alarm outputs (ALARMA, ALARMB, ALARMZ) and a delayed general fault output (ALARMD)
• Features ±15kV ESD protection on all receiver inputs without latch-up
• Includes a capacitor-programmable delay function to ensure error-free operation at slow data rates

Applications

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

Procurement Notes

Verify the specific suffix 'ACPE' corresponds to the 16-pin Plastic DIP package and the 0°C to +70°C commercial temperature range. Confirm that the 'A' grade designation matches the required fault detection thresholds, as other grades like 'B' have different differential threshold specifications. Ensure the ordering information aligns with the intended application environment and thermal requirements.

Selection Notes

Select this component when designing motor control feedback loops or industrial communication interfaces requiring robust fault detection. The MAX3098EACPE is suitable for applications needing three differential channels with explicit status reporting for wiring integrity. Consider the 16-pin PDIP form factor if through-hole mounting is preferred over surface-mount alternatives like SO or QSOP packages.

Part Context

The MAX3098EACPE belongs to the MAX3097E/MAX3098E family of high-speed receivers designed specifically for harsh industrial environments. These devices are engineered to enhance system reliability by identifying physical layer faults before they cause data corruption. The family shares identical pinouts and core functionality, differing primarily in fault detection sensitivity grades and operating temperature ranges.

Replacement Considerations

The MAX3097EACPE is a direct functional substitute within the same package and temperature range, though it features different fault detection thresholds compared to the MAX3098E series.
