ISO7341FCDW

Overview

The ISO7341FCDW is a quad-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It supports data rates up to 25 Mb/s with a propagation delay of 31 ns. The device provides galvanic isolation with an insulation voltage of 3000 Vrms and operates on supply voltages between 3 V and 5.5 V. It features fail-safe low logic output and robust EMC performance. Operating temperatures range from -40°C to 125°C.

Feature Summary

• Quad-channel architecture for multi-signal isolation
• Galvanic isolation with high insulation voltage rating
• Fail-safe low logic output configuration
• Robust electromagnetic compatibility performance

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power metering and energy monitoring
• Inverter and motor drive interfaces

Procurement Notes

Verify the specific suffix 'DW' confirms the 16-SOIC package and tape-and-reel or tube availability as required. Confirm RoHS compliance status matches current manufacturing standards. Ensure the operating temperature range meets system requirements. Validate that the 3/1 channel configuration aligns with circuit design needs.

Selection Notes

Select this component when four isolated channels are required within a single package. The 3/1 configuration allows three inputs to one side and one input to the other. Consider the 25 Mb/s speed limit for high-speed data transmission. Evaluate power consumption against system efficiency targets.

Part Context

This part belongs to the ISO734x family of digital isolators. It offers a compact alternative to traditional transformer or optical isolators. The SOIC-16 package facilitates surface-mount assembly. It integrates CMOS technology for low power operation.

Replacement Considerations

Check ISO7340FCDW for similar specifications with potential pinout differences. Verify ISO7341CDDWR for smaller package options if space is constrained. Confirm electrical parameters match before substitution.
