Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISL3173EIBZ are qualified based on the following critical parameters:

Functional Equivalence: All substitute parts must implement 1/1 full-duplex RS422/RS485 transceiver functionality with surface mount 14-SOIC packaging.

Electrical Compatibility: Supply voltage range (3V ~ 3.6V) and protocol support (RS422/RS485) are mandatory matching criteria. Data rate, receiver hysteresis, and operating temperature ranges may vary within acceptable industrial application tolerances.

Mechanical Compatibility: All qualified substitutes use the 14-SOIC (0.154", 3.90mm Width) package format, ensuring direct PCB footprint compatibility.

Compliance & Status: All substitute parts maintain Active product status and ROHS3 compliance, supporting regulatory and supply chain requirements.

The following substitute parts meet these criteria and are grouped by manufacturer and thermal rating:

• Analog Devices LTC2852 Series: LTC2852CS#PBF, LTC2852IS#PBF, LTC2852HS#PBF
• Analog Devices/Maxim MAX3079 Series: MAX3079EASD+, MAX3079EESD+T

Parameter Comparison

Engineering Selection Recommendations

LTC2852IS#PBF is the primary substitute for the ISL3173EIBZ in applications requiring identical operating temperature range (-40°C ~ 85°C). This part maintains full RS422/RS485 protocol compatibility, 1/1 transceiver configuration, and 14-SOIC packaging. The LTC2852IS#PBF offers higher data rate capability (20Mbps) while maintaining 3V ~ 3.6V supply compatibility and ROHS3 compliance.

LTC2852HS#PBF is suitable for extended temperature applications requiring operation to 125°C. This variant provides the same electrical and mechanical specifications as the LTC2852IS#PBF with expanded thermal range.

LTC2852CS#PBF is applicable for commercial temperature range applications (0°C ~ 70°C) where reduced thermal operating range is acceptable. This option provides the highest inventory availability among LTC2852 variants.

MAX3079EESD+T is compatible with the ISL3173EIBZ operating temperature range (-40°C ~ 85°C) and offers 14-SOIC packaging with ROHS3 compliance. This part is available in high volume (21,297 pcs) in Cut Tape & Digi-Reel packaging format.

MAX3079EASD+ extends operating temperature to 125°C and is suitable for industrial applications requiring enhanced thermal performance.

All substitute parts are Active status products with ROHS3 compliance and REACH unaffected status, supporting regulatory requirements and long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can LTC2852 series parts directly replace the ISL3173EIBZ?

A: Yes. The LTC2852 series maintains identical 1/1 full-duplex RS422/RS485 transceiver functionality, 14-SOIC package format, and 3V ~ 3.6V supply voltage compatibility. Pin-to-pin compatibility and electrical interface characteristics support direct substitution within specified operating temperature ranges.

Q: What is the difference between LTC2852CS#PBF, LTC2852IS#PBF, and LTC2852HS#PBF?

A: These variants differ in operating temperature range. LTC2852CS#PBF operates 0°C ~ 70°C (commercial), LTC2852IS#PBF operates -40°C ~ 85°C (industrial), and LTC2852HS#PBF operates -40°C ~ 125°C (extended industrial). All three maintain identical electrical specifications and 14-SOIC packaging.

Q: How do MAX3079 parts compare to LTC2852 parts?
