ISO7741QDWWQ1

Overview

The ISO7741QDWWQ1 is an automotive-grade, reinforced quad-channel digital isolator manufactured by Texas Instruments. It features a wide-body 16-SOIC (DWW) package with a 0.551-inch (14.00mm) width. The device supports data rates up to 100Mbps and provides a 5000Vrms isolation rating. It operates on a supply voltage range of 2.25V to 5.5V and includes three forward channels and one reverse channel. The component is qualified under AEC-Q100 standards for operation in temperatures ranging from -40°C to 125°C.

Feature Summary

• Reinforced insulation barrier providing robust electromagnetic compatibility performance
• Wide-body 16-SOIC package design accommodating high channel density
• Automotive qualification ensuring reliability in demanding vehicle environments

Applications

• Automotive gateway systems requiring isolated communication interfaces
• Inverter control circuits within electric vehicle powertrains
• Battery management system signal isolation
• On-board charger communication links

Procurement Notes

Verify the specific DWW package variant against standard SOIC dimensions due to the wider footprint. Confirm AEC-Q100 qualification status for your target automotive application tier. Check current lifecycle status as some variants may be transitioning to newer generations. Ensure PCB layout accounts for the increased creepage distance required by the wide-body package geometry.

Selection Notes

Select this part when wide-body packaging is mandatory for enhanced isolation clearance or thermal dissipation. Compare propagation delay specifications if timing precision is critical for your bus protocol. Evaluate the 3/1 channel configuration against applications requiring symmetric bidirectional data flow. Verify that the 100Mbps speed meets the requirements of your specific communication standard.

Part Context

This component belongs to the ISO774x-Q1 family of automotive digital isolators. It utilizes capacitive coupling technology to transmit signals across the isolation barrier without magnetic components. The wide-body package distinguishes it from standard narrow SOIC versions, offering different physical mounting characteristics while maintaining similar electrical performance profiles within the series.

Replacement Considerations

ISO7741QDWWRQ1 is a manufacturer-recommended alternative available in a standard tape-and-reel format rather than tube packaging.
