ISL32374EFBZ Equivalent & Substitute Parts

Part Overview

The ISL32374EFBZ 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 equivalent substitute parts necessary for new designs and ongoing production requirements. The ISL32374EFBZ provides RS422 and RS485 driver functionality with a supply voltage range of 3V to 5.5V and operates across an industrial temperature range of -40°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISL32374EFBZ are qualified based on the following critical parameters:

• Protocol Compatibility: RS422/RS485 driver functionality
• Driver/Receiver Configuration: 4/0 driver-only architecture
• Package Compatibility: 16-SOIC surface mount package with identical 0.154" (3.90mm) width
• Electrical Interface: Compatible supply voltage and operating temperature ranges
• Compliance Standards: ROHS3 compliance and EAR99 classification

The Texas Instruments SN75ALS192D and SN75ALS192DR meet these core substitution criteria. Both devices provide identical 4/0 RS422/RS485 driver functionality in the same 16-SOIC package footprint. However, differences in supply voltage range, operating temperature, and product status must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

SN75ALS192DR is the primary substitute for new designs and production. This device carries Active product status from Texas Instruments, ensuring long-term availability and supply chain stability. The SN75ALS192DR is available in Cut Tape (CT) and Digi-Reel packaging with 17,114 pieces in current inventory. Both the SN75ALS192DR and SN75ALS192D maintain ROHS3 compliance and EAR99 classification, matching the regulatory profile of the ISL32374EFBZ.

SN75ALS192D is available as a Last Time Buy option with 1,201 pieces in inventory, packaged in Tube format. This part remains suitable for applications where supply voltage is constrained to 4.75V to 5.25V and operating temperature does not exceed 70°C.

Applications requiring the full -40°C to 125°C operating temperature range or 3V minimum supply voltage of the ISL32374EFBZ should evaluate alternative driver architectures, as both Texas Instruments substitutes operate within narrower environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can SN75ALS192D and SN75ALS192DR be used interchangeably?

A: Both devices provide identical RS422/RS485 4/0 driver functionality in the 16-SOIC package. The primary difference is product status: SN75ALS192DR is Active with higher inventory availability, while SN75ALS192D is Last Time Buy. Packaging differs (Cut Tape/Digi-Reel versus Tube). For new designs, SN75ALS192DR is preferred.

Q: What are the critical voltage differences between the ISL32374EFBZ and substitute parts?

A: The ISL32374EFBZ operates from 3V to 5.5V, while both SN75ALS192 variants operate from 4.75V to 5.25V. Applications using supply voltages below 4.75V or above 5.25V cannot use the Texas Instruments substitutes without circuit redesign.

Q: Are there temperature range limitations with the substitute parts?

A: Yes. The ISL32374EFBZ operates from -40°C to 125°C, while SN75ALS192D and SN75ALS192DR operate from 0°C to 70°C. Applications requiring extended temperature operation below 0°C or above 70°C must use alternative components.

Q: Is the 16-SOIC package footprint identical across all three parts?

A: Yes. All three devices use the 16-SOIC package with 0.154" (3.90mm) width, enabling direct PCB footprint compatibility without layout modifications.

Q: What is the significance of the Moisture Sensitivity Level (MSL) difference?

A: The ISL32374EFBZ has MSL 3 (168 hours), requiring controlled storage and handling. Both SN75ALS192 variants have MSL 1 (Unlimited), providing greater flexibility in storage and manufacturing environments with less stringent moisture control requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. The ISL32374EFBZ, SN75ALS192D, and SN75ALS192DR are all ROHS3 compliant and carry EAR99 classification, meeting equivalent regulatory requirements.
