ISO6720BDR

Overview

The ISO6720BDR is a dual-channel digital isolator from Texas Instruments featuring capacitive coupling technology. It provides 5000Vrms isolation voltage and supports data rates up to 50Mbps with a typical propagation delay of 11ns. The device operates on a supply voltage range of 1.7V to 5.5V, drawing 2.5mA or 7.9mA depending on the logic side. It offers a common-mode transient immunity (CMTI) of 100kV/µs and functions within a temperature range of -40°C to 125°C in an 8-pin SOIC package.

Feature Summary

• High-speed data transmission capability supporting up to 50Mbps for efficient communication
• Robust electromagnetic compatibility performance with 100kV/µs common-mode transient immunity
• Wide operating voltage range accommodating both 1.8V and 5V logic systems

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment needing high-voltage safety isolation
• Power metering applications involving isolated signal transmission

Procurement Notes

Verify the specific suffix 'BDR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 8-SOIC footprint matches the PCB design constraints. Ensure the component meets RoHS3 compliance standards if mandated by project specifications. Cross-reference the datasheet revision date to confirm current manufacturing status and parameter validity before finalizing procurement orders.

Selection Notes

Select this component when high-speed data integrity is critical alongside robust noise immunity in harsh environments. The 50Mbps rate suits fast serial protocols like SPI or RS-485. Consider the 1.7V minimum supply for low-power embedded designs. The 100kV/µs CMTI ensures reliability in electrically noisy industrial settings compared to lower-immunity alternatives.

Part Context

This part belongs to the ISO672x family of general-purpose basic dual-channel digital isolators. It shares the same pinout and functional architecture as the ISO6721 and ISO6722 but differs in channel directionality. The BDR suffix indicates the standard commercial-grade temperature range and reel packaging configuration used in mass production.

Replacement Considerations

The ISO6720BDRE4 is a lead-free equivalent variant. The ISO6720BDWR serves as a wider-body alternative with identical electrical characteristics. Verify package dimensions and thermal requirements when substituting with these cross-reference parts.
