V62/21610-01XE

Overview

The V62/21610-01XE is a radiation-tolerant quad-channel digital isolator from Texas Instruments, part of the ISOS141 series. It features three forward channels and one reverse channel with bidirectional polarity. The device supports data rates up to 100 Mb/s using capacitive coupling isolation. It operates within a supply voltage range of 2.25 V to 5.5 V and draws 6.8 mA of quiescent current. Key electrical parameters include an insulation voltage of 3000 Vrms, propagation delay of 10.7 ns, and maximum fall time of 3.9 ns. It functions in temperatures from -55°C to +125°C and is housed in an SSOP-16 package.

Feature Summary

• Radiation tolerance for space-enhanced applications
• Quad-channel architecture with asymmetric 3/1 configuration
• Capacitive coupling isolation technology
• Bidirectional signal transmission capability

Applications

• Spacecraft communication systems
• Satellite telemetry and control interfaces
• High-reliability aerospace electronics
• Harsh environment industrial isolation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required radiation tolerance and pinout specifications. Ensure compliance with export regulations as indicated by shipping restrictions. Validate datasheet revisions against the manufacturing date code to guarantee performance consistency for mission-critical deployments.

Selection Notes

Select this component when radiation hardness is mandatory for digital isolation requirements. The asymmetric channel count suits designs needing more forward than reverse data paths. Verify input/output voltage levels align with the 2.25 V to 5.5 V operating range. Consider the SSOP-16 package constraints for PCB layout and thermal management in enclosed aerospace enclosures.

Part Context

This part belongs to the ISOS141 family of space-grade digital isolators. It replaces standard commercial isolators in environments where single-event effects could compromise system integrity. The V62 prefix indicates a military or space-specific qualification tier within Texas Instruments' product portfolio, ensuring stricter testing protocols than general industrial grades.
