ISO7341FCQDWQ1

Overview

The ISO7341FCQDWQ1 is an automotive-grade, low-power quad-channel digital isolator from Texas Instruments. It provides galvanic isolation with a maximum insulation voltage of 3000 Vrms and operates within a supply voltage range of 3 V to 5.5 V. The device supports data rates up to 25 Mb/s with a typical propagation delay of 31 ns. It features a 3/1 channel configuration (three forward, one reverse) in a 16-pin SOIC package. Certified under AEC-Q100, it functions reliably between -40°C and +125°C.

Feature Summary

• Provides robust electromagnetic compatibility performance suitable for demanding automotive environments.
• Delivers high common-mode transient immunity to ensure signal integrity across isolation barriers.
• Offers low power consumption characteristics optimized for energy-efficient system designs.

Applications

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

Procurement Notes

Verify the specific suffix 'F' indicates the correct variant for your design requirements. Confirm that the SOIC-16 package dimensions match your PCB footprint constraints. Ensure the AEC-Q100 qualification aligns with your automotive reliability standards. Check for moisture sensitivity levels if reflow soldering is planned. Validate that the 3000 Vrms insulation rating meets your safety isolation needs.

Selection Notes

Select this component when a quad-channel isolator with asymmetric channel distribution is required. The 3/1 layout suits applications needing multiple input signals and a single return path. Consider the 25 Mb/s speed limit for synchronous communication protocols. Evaluate the 3 V to 5.5 V operating range against your system's logic levels. The automotive qualification makes it suitable for harsh environmental conditions.

Part Context

This part belongs to the ISO734x-Q1 family of digital isolators designed for automotive applications. It shares core specifications with variants like ISO7341CQDWQ1 but may differ in specific marking or packaging details. The family emphasizes low power and robust EMC performance for vehicle networks.

Replacement Considerations

ISO7341CQDWQ1 is a related variant within the same family. Verify if the specific 'F' suffix designation offers distinct functional differences before substitution.
