MAX3097ECEE+

Overview

The MAX3097ECEE+ is a triple RS-485/RS-422 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 utilizes a 16-pin QSOP package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• Detects open-circuit conditions, short-circuit conditions, low differential voltage signals, and common-mode range violations.
• Provides independent alarm outputs for each receiver channel plus a delayed general fault output.
• Features capacitor-programmable delay logic to prevent erroneous fault indications during slow signal edge rates.
• Offers robust electrostatic discharge protection rated at ±15kV (HBM) and ±15kV (IEC Air-Gap).

Applications

• Motor-shaft encoder receivers
• Telecommunications systems
• Embedded systems

Procurement Notes

Verify the specific suffix 'CEE' confirms the commercial temperature range (0°C to +70°C) and the 16-pin QSOP physical package. Ensure the '+T' or standard tape-and-reel designation matches the required manufacturing handling method. Cross-reference the manufacturer's current ordering information to confirm production status and availability before finalizing procurement plans.

Selection Notes

Select this component when high-speed differential signaling up to 32Mbps requires immediate fault detection without external logic. The independent ALARM_ pins allow precise channel monitoring, while the programmable ALARMD pin simplifies system-level error handling. Verify that the -10V to +13.2V common-mode range aligns with the specific bus environment requirements.

Part Context

This device belongs to the MAX3097E/MAX3098E family of high-speed receivers. The MAX3097E variant specifically provides three receivers with fault detection, whereas the MAX3098E offers similar functionality but with different fault threshold characteristics. Both share the same pinout and core architecture designed for industrial reliability.

Replacement Considerations

The MAX3097EESE+ serves as a direct functional replacement offering identical specifications in a 16-pin SO package. Designers must account for the physical footprint differences between the QSOP and SO packages when substituting components.
