ISO7741TBDWRQ1

Overview

The ISO7741TBDWRQ1 is an automotive-grade, quad-channel reinforced digital isolator from Texas Instruments. It features a SOIC-16 package and supports data rates up to 100 Mb/s with a propagation delay of 10.7 ns. The device operates on a supply voltage between 2.25 V and 5.5 V, drawing 6.3 mA of quiescent current. It provides 1500 Vrms insulation voltage and withstands common-mode transients at 100 kV/µs. Operating temperatures range from -40°C to +125°C.

Feature Summary

• Provides reinforced digital isolation for automotive applications
• Features low emissions and high electromagnetic immunity
• Integrates four independent channels in a compact package

Applications

• Automotive engine control units
• Body electronics systems
• Infotainment interfaces

Procurement Notes

Verify the specific suffix 'TB' confirms the required channel configuration and insulation rating. Ensure the Q1 designation matches automotive reliability standards. Confirm the SOIC-16 package width and pinout compatibility with the target PCB layout before finalizing procurement.

Selection Notes

Select this component when reinforced isolation is mandated by safety standards. It is suitable for designs requiring low power consumption alongside high noise immunity. Consider the 100 kV/µs CMTI rating for environments with significant electrical noise.

Part Context

This part belongs to the ISO7741Tx-Q1 family of automotive digital isolators. It utilizes capacitive coupling technology to transmit signals across an isolation barrier. The series is designed to replace bulky magnetic couplers in modern vehicle architectures.

Replacement Considerations

ISO7741BDW is a non-automotive equivalent with similar electrical characteristics but lacks the Q1 qualification.
