ISO7763DBQ

Overview

The ISO7763DBQ is a general-purpose digital isolator from Texas Instruments featuring six independent channels in a 16-SSOP package. It provides 3000Vrms isolation voltage with a data rate of 100Mbps and a common-mode transient immunity (CMTI) of 85kV/µs. The device operates on a supply voltage range of 2.25V to 5.5V, supporting both 3-input/3-output and unidirectional configurations. Key timing parameters include a maximum propagation delay of 16ns and a pulse width distortion of 4.9ns. It functions within an operating temperature range of -55°C to 125°C.

Feature Summary

• Provides reinforced insulation for robust electromagnetic compatibility performance
• Features high-speed capacitive coupling technology for reliable signal transmission
• Offers six independent channels for versatile system integration

Applications

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

Procurement Notes

Verify the specific suffix 'DBQ' indicates the tube packaging format, distinct from the 'DBQR' reel variant. Confirm the component status as discontinued or active through official Texas Instruments channels before finalizing orders. Ensure the design accommodates the 16-SSOP footprint dimensions. Check for any product change notices regarding manufacturing updates.

Selection Notes

Select this component when six isolated channels are required within a compact surface-mount package. The 85kV/µs CMTI rating suits environments with significant noise. Consider the 3000Vrms isolation level against application safety standards. Evaluate the 100Mbps data rate against signal speed requirements. Compare power consumption against other family members if efficiency is critical.

Part Context

This part belongs to the ISO776x series of digital isolators. It shares the same core architecture as variants like ISO7763DBQR but differs in packaging. The series is designed for high-reliability applications across industrial and medical sectors. Other models in the family offer different channel counts or insulation ratings.

Replacement Considerations

ISO7763DBQR is a direct functional substitute with identical electrical characteristics, differing only in tape-and-reel packaging instead of tubes.
