ISO7742TBDWRQ1

Overview

The ISO7742TBDWRQ1 is an automotive-grade, quad-channel reinforced digital isolator from the ISO774xT-Q1 series by Texas Instruments. It features integrated transformer drivers and supports data rates up to 100 Mb/s with a propagation delay of 10.7 ns. The device operates on a supply voltage range of 2.25 V to 5 V and provides an insulation voltage of 1.5 kV (5000 Vrms). It includes 2 forward and 2 reverse channels, with rise/fall times of 3.9 ns and pulse width distortion of 6.2 ns. Operating temperatures range from -40°C to +125°C in a 16-pin SOIC package.

Feature Summary

• Integrated transformer driver for enhanced performance
• Reinforced isolation rating per UL 1577 standards
• High common-mode transient immunity
• Automotive qualification compliant

Applications

• Automotive electronic control units
• Industrial communication interfaces
• General-purpose isolated data transmission

Procurement Notes

Verify the specific suffix 'TB' against official Texas Instruments documentation to confirm the exact insulation rating and package variant. Ensure compatibility with AEC-Q100 requirements for your target application. Confirm that the SOIC-16 footprint matches your PCB design constraints. Check for any recent lifecycle status updates or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when reinforced isolation and integrated transformer drivers are required for automotive applications. It is suitable for designs needing high-speed data transmission with strict EMC requirements. Consider the 16-SOIC package size for space-constrained boards. Verify that the 100 Mb/s data rate meets system timing specifications.

Part Context

This part belongs to the ISO774xT-Q1 family, which offers high-performance digital isolation solutions. The 'TBDW' suffix indicates a specific tape-and-reel packaging option in a wide-body SOIC package. It is designed to replace legacy isolators while providing improved reliability and integration for modern automotive systems.

Replacement Considerations

Check for direct substitutes within the ISO7742 series with different suffixes for varying insulation ratings or packaging options. Ensure any replacement maintains the same channel count and data rate capabilities.
