ISO7760FQDBQRQ1

Overview

The ISO7760FQDBQRQ1 is a six-channel digital isolator from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It features capacitive coupling technology and unidirectional signal transmission across all channels. The device offers a 3000Vrms isolation rating per UL 1577 standards and supports data rates up to 100Mbps. Key electrical parameters include a maximum propagation delay of 11ns, typical rise/fall times of 3.9ns, and a minimum common-mode transient immunity (CMTI) of 85kV/µs. It operates on a supply voltage range of 2.25V to 5.5V within an ambient temperature range of -40°C to +125°C.

Feature Summary

• Six-channel unidirectional digital isolation with capacitive coupling technology
• Automotive-grade reliability certified under AEC-Q100 standards
• High common-mode transient immunity for robust EMC performance
• Supports high-speed data transmission up to 100Mbps

Applications

• Automotive CAN bus systems
• In-vehicle network interfaces
• Industrial control systems requiring galvanic isolation
• Motor control gate drivers

Procurement Notes

Verify the specific suffix 'F' in the part number, as it may indicate a specific tape-and-reel configuration or packaging variant compared to standard versions. Confirm that the DBQR package type matches your PCB footprint requirements. Ensure compliance with RoHS3 directives if required by your manufacturing process. Cross-reference the datasheet revision date to ensure compatibility with latest design guidelines.

Selection Notes

Select this component when six isolated channels are required for unidirectional signaling in automotive environments. It is suitable for designs needing high CMTI to withstand noisy electrical environments. Compare against ISO7760QDBQRQ1 if different packaging or specific parameter tolerances are needed. Consider power consumption and thermal dissipation capabilities within the SSOP-16 package constraints.

Part Context

This device belongs to the ISO776x-Q1 family of high-performance digital isolators. It shares the same core architecture and channel count as other variants in the series but differs in isolation ratings and packaging options. The DBQR package provides a compact solution for space-constrained automotive PCB layouts while maintaining reinforced isolation barriers.

Replacement Considerations

ISO7760QDBQRQ1 is listed as a parameter-equivalent substitute. Verify if the 'F' suffix denotes a specific reel specification or if the parts are functionally identical. Check datasheets for any differences in propagation delay or CMTI specifications between the two part numbers.
