ISO6761FDWR

Overview

The ISO6761FDWR is a six-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It supports data rates up to 50 Mbps with a propagation delay of 11 ns and common-mode transient immunity of 50 kV/µs. The device operates on supply voltages ranging from 1.71 V to 5.5 V, drawing typical currents of 8.3 mA per side. It provides reinforced insulation ratings of 5000 Vrms and functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation for multiple serial communication interfaces
• Features high common-mode transient immunity for noise-sensitive environments
• Supports bidirectional signal transmission across all channels

Applications

• CAN bus isolation
• RS-232 interface isolation
• RS-485 interface isolation
• SPI bus isolation

Procurement Notes

Verify the specific suffix 'FDWR' corresponds to the SOIC-16 package and tape-and-reel quantity. Confirm RoHS compliance status through official manufacturer documentation. Ensure the component meets the required thermal and electrical specifications for the target application environment before finalizing procurement.

Selection Notes

Select this component when six isolated channels are required for general-purpose digital isolation. It is suitable for applications needing 5000 Vrms reinforced isolation and 50 Mbps data throughput. Consider the 16-pin SOIC footprint and wide supply voltage compatibility during circuit design.

Part Context

This part belongs to the ISO676x family of general-purpose digital isolators. It offers a compact solution for isolating microcontrollers, gate drivers, and communication ports. The device integrates capacitive coupling technology to provide reliable signal transmission across isolation barriers.

Replacement Considerations

Check for direct pin-to-pin replacements within the ISO676x series, such as the ISO6760 or ISO6762, ensuring channel configuration and isolation ratings match the original design requirements.
