ISO7721DWVR

Overview

The ISO7721DWVR is a high-speed, reinforced dual-channel digital isolator from Texas Instruments. It features a data rate of 100 Mb/s and operates within a supply voltage range of 2.25 V to 5.5 V. The device provides an isolation rating of 5000 Vrms with a typical propagation delay of 17 ns. It utilizes capacitive coupling technology and is housed in an SOIC-8 package. The component supports unidirectional signal transmission across two forward channels with no reverse channels.

Feature Summary

• High-speed data transmission capability at 100 Mbps
• Reinforced insulation barrier for robust EMC performance
• Capacitive coupling isolation technology

Applications

• Automotive general-purpose systems
• Industrial communication interfaces
• Power monitoring circuits

Procurement Notes

Verify the specific suffix 'Q1' or absence thereof against official datasheets to confirm automotive qualification status. Ensure the SOIC-8 package width matches design constraints. Confirm humidity sensitivity handling requirements during assembly. Validate that the 5000 Vrms rating aligns with system safety standards. Check for RoHS compliance documentation before finalizing procurement.

Selection Notes

Select this component when reinforced isolation is required for dual-channel applications. Consider the 100 Mbps speed for high-frequency digital signals. Evaluate the 17 ns propagation delay against timing budgets. Compare power consumption against other isolators if efficiency is critical. Ensure the operating temperature range meets environmental specifications.

Part Context

This part belongs to the ISO772x family of high-speed digital isolators. It shares architectural similarities with the ISO6721 but offers higher data rates. The DWVR suffix indicates the SOIC-8 package and reel packaging. It complements single-channel variants like the ISO7720 for multi-channel designs.

Replacement Considerations

The ISO7720DWVR is a related variant with identical packaging but lower data rates. Verify channel configuration compatibility as the ISO7721 is strictly dual-channel. Cross-reference isolation ratings with the ISO6721 series for alternative options.
