ISO7762FDBQR

Overview

The ISO7762FDBQR is a six-channel digital isolator from the ISO776x series, manufactured by Texas Instruments. It features four unidirectional channels on one side and two on the other, housed in a 16-SSOP package. The device supports data rates up to 100 Mbps with a typical propagation delay of 11 ns. It operates within a supply voltage range of 2.25 V to 5.5 V and provides an isolation rating of 3000 Vrms. The component exhibits high common-mode transient immunity of 85 kV/µs and functions across an extended temperature range of -55°C to +125°C.

Feature Summary

• Robust electromagnetic compatibility performance with high common-mode transient immunity
• Capacitive coupling technology for signal transmission across the isolation barrier
• Reinforced insulation barrier supporting long-term reliability

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power metering applications with high-voltage separation needs

Procurement Notes

Verify the specific suffix DBQR against the official datasheet to confirm the reel packaging configuration and moisture sensitivity level. Ensure the operating environment matches the specified temperature range and voltage limits. Cross-reference the 16-SSOP footprint dimensions with the PCB layout guidelines provided in the product documentation to ensure mechanical compatibility.

Selection Notes

Select this component when a six-channel isolator with reinforced ratings is required. The 4/2 channel split suits asymmetric data flow architectures. Consider the 100 Mbps speed limit for bandwidth requirements. The SSOP package offers a compact solution for space-constrained designs compared to wider SOIC options.

Part Context

This part belongs to the ISO776x family of high-speed digital isolators. It shares architectural similarities with the ISO7762DBQR but differs in specific qualification or packaging variants. The family utilizes capacitive isolation technology to provide robust signal transmission while maintaining electrical isolation between circuit domains.

Replacement Considerations

The ISO7762DBQR is a related variant within the same family. Verify if the specific insulation rating or qualification status meets the design requirements before substitution.
