ISO7760FDBQ

Overview

The ISO7760FDBQ is a high-performance, six-channel digital isolator from Texas Instruments designed for robust electromagnetic compatibility. It features capacitive coupling technology with a 3000-Vrms isolation rating per UL 1577. The device supports data rates up to 100 Mbps and operates within a supply voltage range of 2.25 V to 5.5 V. Key electrical parameters include a propagation delay of 11 ns, a common-mode transient immunity of 85 kV/µs, and a maximum power dissipation of 292 mW. It functions unidirectionally across all six channels and is housed in a 16-pin SSOP package suitable for surface mount installation.

Feature Summary

• Provides reinforced insulation for six independent signal channels using capacitive coupling technology.
• Engineered for high-speed data transmission with support for rates up to 100 Mbps.
• Ensures system reliability through high common-mode transient immunity of 85 kV/µs.
• Delivers robust electromagnetic compatibility performance for demanding industrial environments.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Automotive electronic control units
• Power metering and energy management systems

Procurement Notes

Verify the specific suffix 'F' indicates the required temperature grade and packaging configuration. Confirm the DBQ package variant aligns with your PCB footprint requirements. Ensure the component meets AEC-Q100 standards if used in automotive applications. Cross-reference the datasheet revision date to confirm current specifications. Validate that the 3000-Vrms rating satisfies your system's isolation voltage requirements.

Selection Notes

Select this component when six isolated channels are necessary for signal integrity in noisy environments. The 100 Mbps speed suits applications requiring faster data throughput than standard isolators. Consider the SSOP-16 package for space-constrained designs. Evaluate the 85 kV/µs CMTI for circuits exposed to rapid voltage transients. Compare against other ISO776x variants if different isolation ratings or channel counts are needed.

Part Context

This part belongs to the ISO776x family of high-speed digital isolators. The family offers both five-thousand-volt and three-thousand-volt isolation options depending on the package type. The ISO7760 specifically provides six channels, making it distinct from four-channel or single-channel alternatives. It utilizes silicon dioxide-based capacitive isolation for long-term stability and low power consumption compared to magnetic counterparts.

Replacement Considerations

Direct substitutes include other ISO776x-Q1 variants with similar channel counts and isolation ratings. Verify pinout compatibility before swapping with non-TI equivalents. Check if alternative packages offer the same thermal and electrical characteristics. Ensure any replacement maintains the required 85 kV/µs common-mode transient immunity level.
