MAX3098EAESE

Overview

The MAX3098EAESE+ is a triple RS-422/RS-485 receiver featuring integrated fault-detection circuitry and dedicated fault-status outputs. It operates on a single +3V to +5.5V supply with a typical current of 4mA. The device supports data rates up to 32Mbps and provides ±15kV ESD protection across all inputs. It detects open-circuit, short-circuit, low differential voltage, and common-mode range violations. The part 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 alarm outputs for each receiver channel plus a delayed universal fault output
• Features capacitor-programmable delay to prevent erroneous fault indications at slow edge rates
• Includes ±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 'AESE' corresponds to the required -40°C to +85°C temperature grade and 16-pin SO package. Confirm that the 'EA' variant meets the necessary differential threshold requirements compared to other grades like 'EB'. Ensure ordering documentation matches the exact manufacturer part number to avoid functional discrepancies.

Selection Notes

Select this component when designing motor control feedback loops or industrial communication networks requiring high-speed signal integrity. The device is suitable for environments where cable faults such as shorts or opens must be detected immediately. Consider the capacitor-programmable delay feature if the application involves signals with slow rise times to avoid false alarms.

Part Context

This component belongs to the MAX3097E/MAX3098E family of rugged, low-power receivers designed for harsh industrial environments. The MAX3098E specifically offers three receiver channels, making it distinct from dual-channel alternatives. It serves as a direct upgrade to legacy industry-standard devices by providing enhanced fault detection capabilities without increasing pin count.
