ISO6520FREUR

Overview

The ISO6520FREUR is a dual-channel, unidirectional digital isolator from Texas Instruments, housed in an 8-pin VSON package. It supports data rates up to 50 Mb/s with a propagation delay of 11 ns and rise/fall times of 5.3 ns. The device operates on supply voltages between 1.71 V and 5.5 V. It functions within a temperature range of -40°C to +125°C and features no shutdown control.

Feature Summary

• Provides functional isolation for two independent signal channels
• Supports unidirectional data transmission at high speeds
• Operates across a wide industrial temperature range

Applications

• Industrial process control systems
• Medical equipment signal isolation
• Power metering applications

Procurement Notes

Verify the specific suffix FREUR to confirm the VSON-8 package type and tape-and-reel packaging configuration. Ensure compatibility with the required 1.71 V to 5.5 V supply voltage range and check humidity sensitivity handling requirements during assembly. Confirm that the unidirectional channel orientation matches the circuit design needs.

Selection Notes

Select this component when a compact solution for dual-channel galvanic isolation is required. It is suitable for designs needing 50 Mbps throughput without shutdown functionality. Consider the VSON-8 footprint for space-constrained PCB layouts. Verify that the 100 kV/µs common-mode transient immunity meets system noise immunity standards.

Part Context

This part belongs to the ISO652x family of general-purpose dual-channel functional isolators. It utilizes capacitive coupling technology to provide electrical isolation between input and output sides. The series is designed for applications requiring reliable signal transmission across isolated boundaries in noisy environments.

Replacement Considerations

ISO6520FDR offers identical electrical specifications but uses an SOIC-8 package instead of VSON-8.
