ISL32174EIBZ Equivalent & Substitute Parts

Part Overview

The ISL32174EIBZ is a 4/0 Driver RS422/RS485 interface IC manufactured by Renesas Electronics Corporation in a 16-SOIC surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The part operates across a 3V to 5.5V supply range with a maximum data rate of 32Mbps and is rated for industrial temperature ranges from -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISL32174EIBZ is determined by the following critical parameters:

• Protocol compatibility: RS422/RS485 interface standard
• Driver/receiver configuration: 4/0 (4 drivers, 0 receivers)
• Package type: 16-SOIC surface mount form factor
• Electrical interface: Pin-compatible pinout

The identified substitute parts (SN75ALS192D and SN75ALS192DR) meet the core functional requirements of protocol support, driver count, and package compatibility. Both Texas Instruments alternatives operate as RS422/RS485 drivers in the same 16-SOIC package configuration, enabling direct functional replacement in applications where the ISL32174EIBZ is no longer available.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing system support, SN75ALS192DR is the preferred substitute. This part maintains active product status with Texas Instruments, ensuring long-term availability and supply chain stability. The SN75ALS192DR is available in Cut Tape and Digi-Reel packaging formats with substantial inventory levels (17,114 pcs), supporting both prototype and production-volume requirements.

SN75ALS192D represents a secondary option, classified as Last Time Buy status. While functionally equivalent, this variant has limited future availability and should be considered only when SN75ALS192DR supply is constrained.

Both substitute parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications as the original ISL32174EIBZ, maintaining regulatory consistency for international distribution.

Frequently Asked Questions (FAQ)

Q: Can SN75ALS192D or SN75ALS192DR be used as direct replacements for ISL32174EIBZ?

A: Yes. Both parts share identical RS422/RS485 protocol support, 4/0 driver/receiver configuration, and 16-SOIC package geometry. Pin-level compatibility enables direct substitution in existing PCB layouts without redesign.

Q: What are the voltage supply differences between the main part and substitutes?

A: The ISL32174EIBZ operates across 3V to 5.5V, while both SN75ALS192 variants operate across 4.75V to 5.25V. Systems designed for the full 3V to 5.5V range of the ISL32174EIBZ must be evaluated for compatibility with the narrower 4.75V to 5.25V window of the substitutes.

Q: Are there temperature range considerations for substitution?

A: The ISL32174EIBZ supports -40°C to 85°C operation, while SN75ALS192 variants support 0°C to 70°C. Applications requiring extended low-temperature operation below 0°C or high-temperature operation above 70°C cannot use the Texas Instruments substitutes without thermal management review.

Q: Which substitute part should be selected for new production?

A: SN75ALS192DR is recommended for new designs. This part maintains active product status, offers the highest inventory availability, and is available in multiple packaging formats (Cut Tape and Digi-Reel) suitable for both prototype and high-volume manufacturing.

Q: Are all parts RoHS compliant?

A: Yes. The ISL32174EIBZ and both SN75ALS192 variants are ROHS3 compliant, meeting environmental and regulatory requirements for commercial and industrial applications.
