MAX3098EAESE+

Overview

The MAX3098EAESE+ 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 receiver channel, identifying open-circuit, short-circuit, low differential voltage, and common-mode range violations. It includes ±15kV ESD protection via Human Body Model and IEC 1000-4-2 standards. The component is housed in a 16-pin SO package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Detects open-circuit, short-circuit, low differential voltage, and common-mode range violations
• Provides independent fault-status outputs for each receiver channel
• Includes capacitor-programmable delay to prevent erroneous fault indications at slow edge rates
• Offers robust electrostatic discharge protection without requiring external components

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 range. Confirm RoHS compliance status through manufacturer resources. Ensure the selected variant matches the required industrial or commercial operating conditions before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring high-speed differential signaling with integrated fault detection capabilities. The device is suitable for applications needing reliable signal integrity monitoring in noisy environments. Consider the extended common-mode input range and ESD ratings for harsh industrial settings.

Part Context

This part belongs to the MAX3097E/MAX3098E family of high-speed RS-485/RS-422 receivers. The MAX3098E variant specifically provides three receiver channels with fault detection, distinguishing it from other interface ICs that may lack diagnostic features or support fewer channels.

Replacement Considerations

Direct functional replacements include other Maxim Integrated triple RS-485 receivers with fault detection. Verify pin compatibility and electrical specifications such as data rate and supply voltage when substituting.
