MAX3098EBESE+T

Overview

The MAX3098EBESE+T 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 a capacitor-programmable delayed fault output (ALARMD) to prevent erroneous alarms at slow edge rates. ESD protection is rated at ±15kV (HBM), ±15kV (IEC Air-Gap), and ±8kV (IEC Contact Discharge). 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 violation faults
• Provides independent fault-status outputs for each receiver channel alongside a programmable delayed general fault output
• Offers robust electrostatic discharge protection meeting IEC 1000-4-2 standards without external components

Applications

• Motor-shaft encoder receivers
• Telecommunications systems
• Embedded systems requiring high-speed fault detection

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and temperature grade. Confirm RoHS compliance status through current datasheets or distributor declarations. Ensure the source document matches the requested part number exactly to avoid discrepancies in electrical characteristics or pin configurations.

Selection Notes

Select this component when designing systems that require simultaneous monitoring of three differential signal lines for integrity issues. The integrated fault detection eliminates the need for external monitoring circuits. Verify that the application environment stays within the specified -40°C to +85°C temperature range and that the supply voltage remains between 3V and 5.5V.

Part Context

This device belongs to the MAX3097E/MAX3098E family of high-speed receivers. The MAX3098 variant specifically provides three receiver channels, whereas the MAX3097 typically offers fewer. The 'B' suffix in the ordering code denotes specific fault detection thresholds optimized for certain industrial applications compared to other grades in the series.

Replacement Considerations

MAX3098EAESE+T: Same function and pinout but with extended commercial temperature range (-40°C to +85°C vs 0°C to +70°C for some variants, verify specific B-grade temp range in datasheet). MAX3098EBCEE+T: Identical electrical specifications but utilizes a QSOP-16 package instead of SO-16.
