ISO7721FDWVR

Overview

The ISO7721FDWVR is a high-speed, robust EMC reinforced dual-channel digital isolator from Texas Instruments. It features capacitive coupling technology with a data rate of 100 Mb/s and an insulation voltage of 5000 Vrms. The device operates on a supply voltage range of 2.25 V to 5.5 V, consuming 7.3 mA of operating current. Key electrical parameters include a propagation delay of 17 ns, rise/fall times of 3.9 ns, and pulse width distortion of 0.5 ns. It supports unidirectional signal transmission in an SOIC-8 package, functioning within a temperature range of -55°C to +125°C.

Feature Summary

• Provides reinforced isolation for enhanced safety and reliability in demanding environments
• Utilizes capacitive coupling technology to ensure robust electromagnetic compatibility performance
• Supports high-speed data transmission at rates up to 100 Mb/s for efficient communication

Applications

• Automotive electronic control units requiring certified isolation
• Industrial automation systems with high noise immunity needs
• Medical equipment requiring reinforced galvanic isolation

Procurement Notes

Verify the specific suffix 'F' confirms the reinforced isolation rating and automotive-grade qualification if required by your design specifications. Ensure the SOIC-8 package dimensions match your PCB footprint constraints. Confirm that the -55°C to +125°C operating temperature range aligns with your environmental conditions. Check datasheet details for moisture sensitivity levels and recommended soldering profiles to prevent assembly defects.

Selection Notes

Select this component when reinforced isolation standards are mandatory rather than basic isolation. Consider the 100 Mb/s data rate sufficient for your application's bandwidth requirements. Evaluate the 7.3 mA supply current against power budget constraints. The unidirectional channel configuration suits applications where signal flow is strictly one-way across the isolation barrier.

Part Context

This part belongs to the ISO7721 family of digital isolators designed for high-performance isolation applications. The 'F' designation typically indicates reinforced isolation characteristics compliant with stricter safety standards compared to basic isolation variants. The DWVR suffix denotes the SOIC-8 surface-mount package with tape-and-reel packaging for automated assembly processes.

Replacement Considerations

Check for ISO7721FQDWVRQ1 for automotive qualified versions with similar specs. Verify ISO7721FDWV as a potential tube-packaged alternative if reel quantities are not required. Ensure any substitute maintains the same reinforced isolation rating and SOIC-8 footprint.
