ISO6763FQDWRQ1

Overview

The ISO6763FQDWRQ1 is a six-channel digital isolator from Texas Instruments, designed for automotive applications. It features capacitive coupling technology with a data rate of 50 Mb/s and an insulation voltage of 5000 Vrms. The device operates within a supply voltage range of 1.71 V to 5.5 V and consumes 14.4 mA of operating current. It provides bidirectional signal transmission across three forward and three reverse channels. Key timing parameters include an 11 ns propagation delay, 4.5 ns rise/fall times, and 7 ns pulse width distortion. It functions reliably between -40°C and +125°C in a SOIC-16 package.

Feature Summary

• Six-channel bidirectional digital isolation using capacitive coupling technology
• Automotive-grade qualification supporting high-temperature operation up to 125°C
• High-speed data transmission capability at 50 Mb/s per channel
• Robust insulation performance rated at 5000 Vrms

Applications

• Automotive general-purpose isolated communication interfaces
• Inverter gate drive circuits requiring high common-mode transient immunity
• Isolated microcontroller unit (MCU) peripheral connections
• Industrial automation systems demanding reliable signal integrity

Procurement Notes

Verify the specific suffix 'FQDWRQ1' to confirm the SOIC-16 package, tape-and-reel packaging format, and automotive grade classification. Ensure compatibility with the required 1.71 V to 5.5 V supply voltage range and check that the bidirectional channel configuration meets the system's signal flow requirements before finalizing procurement.

Selection Notes

Select this component when a six-channel bidirectional isolator is required for automotive environments. It is suitable for designs needing 50 Mb/s data rates and 5000 Vrms isolation strength. Consider the 14.4 mA power consumption and SOIC-16 footprint during PCB layout. Verify that the bidirectional nature aligns with the application's signal directionality needs compared to unidirectional alternatives.

Part Context

This part belongs to the ISO6763 family of automotive digital isolators. It shares the SOIC-16 package and capacitive coupling technology with other members like the ISO6762FQDWRQ1. The primary distinction lies in the channel count and directionality; the ISO6763 offers six bidirectional channels, whereas variants may offer different configurations or unidirectional paths within the same series.

Replacement Considerations

The ISO6762FQDWRQ1 is a related part but differs in channel configuration and directionality. Verify pinout compatibility and functional equivalence before substitution. No direct public substitute part numbers are confirmed for identical specifications.
