ISO7763FDBQR

Overview

The ISO7763FDBQR is a high-speed, robust EMC reinforced six-channel digital isolator from Texas Instruments. It features three forward and three reverse channels with capacitive coupling technology. The device supports data rates up to 100 Mb/s and offers an insulation voltage of 3000 Vrms for the DBQ package. It operates within a supply voltage range of 2.25 V to 5.5 V and maintains a typical propagation delay of 16 ns. The component is housed in a 16-lead SSOP package and is designed for applications requiring high common-mode transient immunity.

Feature Summary

• Provides reinforced isolation capabilities compliant with UL 1577 standards for safety-critical designs.
• Delivers robust electromagnetic compatibility performance with high common-mode transient immunity.
• Integrates six independent signal channels in a compact surface-mount package.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety barriers
• Power metering and energy management circuits

Procurement Notes

Verify that the specific suffix 'FDBQR' corresponds to the required 3000 Vrms insulation rating and SSOP-16 package configuration. Confirm that the reinforced isolation designation meets the safety certification requirements of the target application. Ensure compatibility with the intended operating temperature range and supply voltage specifications before finalizing procurement orders.

Selection Notes

Select this component when reinforced isolation ratings are mandatory rather than basic isolation. Consider the 16-lead SSOP footprint constraints against available PCB real estate. Evaluate the 100 Mb/s data rate capability against system bandwidth requirements. Compare power consumption characteristics against alternative isolators if low-power operation is a primary design constraint.

Part Context

This part belongs to the ISO776x family of high-performance digital isolators. It shares architectural similarities with other members like the ISO7763FDWR but differs in packaging and specific insulation ratings. The family is engineered for demanding environments where signal integrity and electrical safety are paramount.

Replacement Considerations

The ISO7763FDW serves as a tube-packaged alternative within the same functional family. Verify that the replacement matches the required insulation voltage and package dimensions for direct board integration without redesign.
