ISO7760DBQ

Overview

The ISO7760DBQ is a high-speed, robust EMC reinforced six-channel digital isolator manufactured by Texas Instruments. It utilizes capacitive coupling technology to provide electrical isolation between circuits. The device operates within a supply voltage range of 2.25 V to 5.5 V and supports data rates up to 100 Mb/s. Key electrical parameters include an insulation voltage of 3000 Vrms, a maximum propagation delay of 16 ns, and a minimum common-mode transient immunity (CMTI) of 85 kV/µs. It features six unidirectional channels with no reverse channels, housed in a 16-SSOP package.

Feature Summary

• Provides reinforced isolation for six independent signal channels using capacitive coupling technology.
• Ensures high noise immunity with a common-mode transient immunity rating of 85 kV/µs.
• Supports high-speed data transmission with a maximum data rate of 100 Mb/s.
• Operates reliably across an extended industrial temperature range from -55°C to +125°C.

Applications

• Industrial automation systems requiring galvanic isolation
• Automotive electronic control units (ECUs)
• Medical equipment with safety isolation requirements
• Power metering and energy management systems

Procurement Notes

Verify the specific suffix 'DBQ' to confirm the tube packaging format, as other suffixes like 'DBQR' indicate tape-and-reel options. Ensure compatibility with AEC-Q100 standards if automotive qualification is required, noting that the Q1 variant may be preferred for strict automotive grade specifications. Confirm lead times and availability directly with authorized distributors, as stock levels fluctuate.

Selection Notes

Select this component when six isolated bidirectional or unidirectional channels are needed in a single package. Compare against the ISO7740 series if fewer channels suffice but higher insulation voltage is required. Consider the ISO7760QDBQRQ1 for explicit automotive qualification requirements. Evaluate power consumption and thermal dissipation capabilities relative to the SSOP-16 package constraints.

Part Context

This part belongs to the ISO776x family of high-speed digital isolators from Texas Instruments. It shares architectural similarities with the ISO773x and ISO774x series but offers a higher channel count. The DBQ suffix specifically denotes the tube packaging option, distinguishing it from reel-based variants like DBQR. It serves as a general-purpose solution for multi-channel isolation needs.

Replacement Considerations

ISO7760FQDBQRQ1 is listed as a parameter-equivalent substitute. Verify pinout compatibility and packaging differences before substitution. Check for any updates in the latest datasheet regarding recommended replacements or end-of-life notices.
