ISO6741FQDWRQ1

Overview

The ISO6741FQDWRQ1 is an automotive-grade, quad-channel digital isolator from Texas Instruments. It features a 3/1 channel configuration with unidirectional signal paths. The device supports data rates up to 50Mbps and provides reinforced isolation of 5000Vrms. It operates within a supply voltage range of 1.71V to 1.89V for the 1.8V logic side and 2.25V to 5.5V for the 3.3V/5V side. Key electrical parameters include a maximum propagation delay of 18ns, typical rise/fall times of 2.6ns, and a common-mode transient immunity (CMTI) of 100kV/µs. It is housed in a 16-pin SOIC package.

Feature Summary

• Provides robust electromagnetic compatibility (EMC) capabilities suitable for automotive environments
• Features integrated capacitive coupling technology for galvanic isolation
• Supports specific 1.8V logic levels on one side alongside standard 3.3V/5V support on the other

Applications

• Automotive CAN bus systems requiring high-speed isolated communication
• In-vehicle networks demanding enhanced EMC performance
• General-purpose automotive digital isolation interfaces

Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and temperature grade. Confirm AEC-Q100 qualification status for automotive compliance. Check datasheet revisions for any recent parameter updates or pinout corrections before finalizing design integration.

Selection Notes

Select this component when 50Mbps speed and 100kV/µs CMTI are required for automotive applications. The 3/1 channel layout suits designs needing three inputs on one side and one output on the other. Ensure power supply rails match the specified 1.8V and 2.25V-5.5V ranges for proper operation.

Part Context

This device belongs to the ISO674x-Q1 family of general-purpose reinforced quad-channel automotive digital isolators. It complements other variants like the ISO6740 and ISO6742 by offering specific channel configurations and logic voltage support tailored for robust automotive network isolation.

Replacement Considerations

ISO6741QDWQ1 is a related variant within the same family. Verify channel count, data rate, and isolation voltage specifications against current requirements before substitution.
