MAX3097EESE RS422/RS485 Receiver Interface IC - Equivalent & Substitute Parts

Part Overview

The MAX3097EESE is a 0/3 receiver interface IC designed for RS422 and RS485 serial communication protocols, packaged in a 16-SOIC surface mount configuration. This component is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design support and procurement continuity. The part operates across a 3V to 5.5V supply range with a maximum data rate of 32 Mbps and receiver hysteresis of 40 mV, making it suitable for industrial and commercial serial communication applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX3097EESE is determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: RS422 and RS485 serial communication standards
• Receiver Configuration: 0/3 driver/receiver count
• Receiver Hysteresis: 40 mV threshold specification
• Data Rate: 32 Mbps maximum throughput
• Supply Voltage Range: 3V to 5.5V operation
• Package Type: 16-SOIC surface mount form factor
• Electrical Characteristics: Identical receiver input specifications

The substitute parts are categorized as follows:

Direct Substitute (Packaging Variant): MAX3097EESE+ maintains identical electrical specifications with active product status and improved RoHS3 compliance.

Manufacturer Recommended Substitute: MAX3097ECSE+ provides full electrical equivalence with extended inventory availability, with the exception of operating temperature range limited to 0°C ~ 70°C.

Parametric Equivalents: MAX3098EAESE+ and MAX3098EBESE+ offer identical electrical performance and thermal operating range (-40°C ~ 85°C) with different internal configurations within the MAX3098 base product line.

Parameter Comparison

Engineering Selection Recommendations

For Extended Temperature Range Applications (-40°C to 85°C): Select MAX3098EAESE+ or MAX3098EBESE+ as parametric equivalents. Both parts maintain full electrical compatibility with the original MAX3097EESE specification while offering active product status and ROHS3 compliance.

For Standard Temperature Range Applications (0°C to 70°C): MAX3097ECSE+ is the manufacturer-recommended substitute, providing the highest inventory availability (100,398 units) with ROHS3 compliance and active product status.

For Direct Replacement with Minimal Design Changes: MAX3097EESE+ serves as the direct substitute, maintaining identical electrical specifications and thermal operating range with improved RoHS compliance status.

Compliance Consideration: All substitute parts are ROHS3 compliant, addressing regulatory requirements that the original obsolete part does not meet. The original MAX3097EESE is RoHS non-compliant and should be replaced in new designs or production runs requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can MAX3097ECSE+ be used as a direct replacement for MAX3097EESE in all applications?

A: MAX3097ECSE+ is electrically equivalent across all critical parameters with one exception: the operating temperature range is limited to 0°C ~ 70°C compared to the original -40°C ~ 85°C. Applications requiring extended temperature operation below 0°C or above 70°C must use MAX3098EAESE+ or MAX3098EBESE+ instead.

Q: What is the difference between MAX3097EESE+ and MAX3098EAESE+?

A: Both parts are parametric equivalents with identical electrical specifications, receiver hysteresis, data rate, and thermal operating range (-40°C ~ 85°C). The difference lies in the base product line designation (MAX3097 versus MAX3098). Both are suitable for direct substitution in RS422/RS485 receiver applications.

Q: Are all substitute parts pin-compatible with the original MAX3097EESE?

A: All substitute parts share the identical 16-SOIC package configuration (0.154", 3.90mm width) and maintain the same 0/3 receiver configuration. Pin compatibility is maintained across all listed substitutes.

Q: Why should I transition from MAX3097EESE to an active substitute part?

A: The MAX3097EESE is classified as obsolete, which creates procurement risk and supply chain uncertainty. Active substitute parts ensure long-term availability, support from the manufacturer, and compliance with current regulatory standards including ROHS3 requirements.

Q: Does the packaging designation (Tube) affect electrical performance?

A: Packaging designation refers to the shipping and storage format only and does not affect electrical performance or functionality. All parts maintain identical electrical specifications regardless of packaging type.
