MAX3098EBCPE

Overview

The MAX3098EBCPE is a triple RS-422/RS-485 receiver featuring 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, supporting an extended common-mode 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 Plastic DIP package and functions within a 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 universal fault output
• Includes capacitor-programmable delay to prevent erroneous fault indications at slow edge rates
• Offers ±15kV ESD protection compatible with IEC 1000-4-2 standards

Applications

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

Procurement Notes

Verify the specific suffix 'BCPE' corresponds to the 16-pin Plastic DIP package and the 0°C to +70°C industrial temperature range. Confirm that the B-grade fault thresholds align with system requirements, as they differ from standard grades. Ensure compatibility with existing PCB footprints designed for PDIP-16 packages before finalizing procurement orders.

Selection Notes

Select this component when motor control applications require simultaneous monitoring of three differential channels for signal integrity faults. The B-grade threshold specifications are suitable for specific encoder interfaces where standard thresholds may not apply. Consider the Plastic DIP package if through-hole mounting is required for mechanical stability in high-vibration environments.

Part Context

This part belongs to the MAX3097E/MAX3098E family of triple receivers designed for motor shaft encoders. While the MAX3097E offers standard fault thresholds, the MAX3098E provides alternative threshold options (A-grade and B-grade) to accommodate different encoder signal levels. The BCPE suffix specifically denotes the plastic DIP variant within this industrial temperature range series.

FAQ

What distinguishes the MAX3098E from the MAX3097E?

The MAX3098E features alternative fault-detection receiver differential threshold voltages (available in A-grade and B-grade), whereas the MAX3097E uses standard thresholds.

How is the delayed fault output configured?

The ALARMD output delay is set by connecting a capacitor between the DELAY pin and GND. The delay time depends on the capacitance value and the supply voltage.

What types of faults can the MAX3098E detect?

It detects open-circuit conditions, short-circuit conditions, low differential input voltage signals, and inputs exceeding the common-mode voltage range.
