ISO6742QDWWRQ1

Overview

The ISO6742QDWWRQ1 is an automotive-grade, general-purpose quad-channel digital isolator from Texas Instruments. It features four independent isolation channels with a 2/2 channel configuration (two forward, two reverse). The device supports data rates up to 50 Mb/s and offers a common-mode transient immunity of 100 kV/µs. It operates within a supply voltage range of 1.71 V to 5.5 V and is housed in a 16-pin SOIC (DWW) package. The component is rated for operation between -40°C and +125°C.

Feature Summary

• Provides reinforced insulation capabilities suitable for automotive applications
• Supports functional safety system design documentation
• Features high common-mode transient immunity for noise resilience

Applications

• Automotive electronic control units
• Inverter gate drive circuits
• CAN bus interface isolation

Procurement Notes

Verify the complete part number including suffixes such as 'W' or 'R' to ensure correct packaging and tape-and-reel specifications. Confirm that the specific variant matches the required channel directionality and logic support levels. Cross-reference the manufacturer's latest datasheet for any updates on recommended operating conditions or pin configurations before finalizing procurement orders.

Selection Notes

Select this component when a quad-channel solution with reinforced isolation is required for automotive systems. Ensure the application demands a 50 Mbps data rate and operates within the specified 1.71 V to 5.5 V supply range. Consider the 16-pin SOIC package constraints and thermal dissipation requirements relative to the board layout and ambient temperature conditions.

Part Context

This device belongs to the ISO674x-Q1 family of general-purpose reinforced quad-channel automotive digital isolators. It is designed to replace bulky magnetic couplers in space-constrained automotive designs. The series supports various logic families and provides robust signal transmission across isolation barriers while maintaining compliance with automotive reliability standards.

Replacement Considerations

Check for ISO6742FQDWWRQ1 if different packaging or specific functional safety certification levels are required. Verify compatibility with ISO6742QDWRQ1 variants regarding channel count and directionality.
