ISO6520REUR

Overview

The ISO6520REUR is a dual-channel, unidirectional digital isolator from Texas Instruments featuring capacitive coupling technology. It provides functional isolation with a data rate of 50 Mb/s and supports 1.8V logic levels. The device operates within a supply voltage range of 1.71 V to 5.5 V and exhibits a propagation delay of 11 ns. It is housed in an 8-pin VSON package and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation for two independent signal channels using capacitive coupling technology.
• Supports high-speed data transmission at rates up to 50 Mbps with low propagation delay.
• Designed for compatibility with 1.8V logic systems while maintaining wide supply voltage flexibility.

Applications

• RS-232 communication interfaces
• RS-485 bus networks
• SPI peripheral connections

Procurement Notes

Verify the specific REU suffix indicates the VSON-8 package configuration. Confirm RoHS compliance status through official documentation. Ensure the component matches the active product status listed by the manufacturer before integration into production designs.

Selection Notes

Select this component when bidirectional signal flow is not required. The unidirectional nature suits applications where data moves strictly from source to destination. Consider the 2/0 channel configuration for isolated power or ground domain separation needs.

Part Context

This part belongs to the ISO652x family of general-purpose dual-channel functional isolators. It shares architectural similarities with variants like the ISO6521 but differs in channel directionality and specific electrical characteristics defined by the datasheet specifications.

Replacement Considerations

Check for ISO6520FREUR as a potential alternative with similar pinout and functionality. Verify that any substitute maintains the same VSON-8 package dimensions and thermal performance requirements for direct board replacement.
