MAX3098EACEE

Overview

The MAX3098EACEE 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 channel and a delayed general fault output. It provides ±15kV ESD protection via Human Body Model, ±15kV IEC 1000-4-2 Air-Gap Discharge, and ±8kV Contact Discharge. The extended common-mode range spans from -10V to +13.2V. It is housed in a 16-pin QSOP package and functions within 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.
• Includes capacitor-programmable delay for the ALARMD output to prevent erroneous fault indications at slow edge rates.
• Offers robust electrostatic discharge protection rated at ±15kV for both Human Body Model and IEC 1000-4-2 Air-Gap Discharge methods.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact package type and temperature rating. Confirm RoHS compliance status through manufacturer datasheets or authorized distributors before procurement. Ensure that the selected variant matches the required environmental operating conditions for the intended application environment.

Selection Notes

Select this component when designing motor control feedback loops requiring high-speed signal reception with integrated fault detection. The MAX3098EACEE is specifically suited for applications needing three independent channels with distinct alarm outputs. Consider the 16-pin QSOP package dimensions if board space is constrained compared to standard industry solutions.

Part Context

This part belongs to the MAX3097E/MAX3098E family of high-speed receivers designed for industrial environments. While functionally similar to the MAX3097E, the MAX3098E offers specific fault-detection threshold characteristics optimized for different signal integrity requirements. Both variants share the same core architecture for handling RS-485/RS-422 protocols.

Replacement Considerations

The MAX3097EACEE is a functional substitute within the same family, sharing identical pinouts and core specifications. Verify that the fault-detection thresholds of the replacement part align with the specific design requirements of the target application circuit.
