ISO7761QDBQQ1

Overview

The ISO7761QDBQQ1 is a six-channel digital isolator from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It features a 5/1 channel configuration (five forward, one reverse) in a 16-SSOP package. Key electrical parameters include a data rate of 100 Mb/s, insulation voltage of 3000 Vrms, and propagation delay of 11 ns. The device operates on a supply voltage range of 2.25 V to 5.5 V, with typical supply currents of 11.5 mA and 30.5 mA. It supports an operating temperature range of -40°C to +125°C and utilizes capacitive coupling technology.

Feature Summary

• Automotive-grade robustness with AEC-Q100 certification for reliable operation in demanding environments.
• High electromagnetic compatibility performance ensuring signal integrity in noisy industrial settings.
• Six-channel isolation architecture providing efficient space-saving solutions for complex circuit designs.

Applications

• Automotive electronic control units requiring isolated communication interfaces
• Industrial automation systems needing robust signal isolation
• Motor drive circuits utilizing high-speed digital isolation

Procurement Notes

Verify the specific suffix QQQ1 indicates tube packaging distinct from QRQ1 tape-and-reel variants. Confirm current production status as documentation indicates potential obsolescence or end-of-life phases for this specific part number. Ensure compatibility with existing PCB footprints for 16-SSOP packages during procurement planning.

Selection Notes

Select this component when automotive qualification and reinforced isolation are required for six-channel applications. Compare against ISO7761FQDBQRQ1 if tape-and-reel packaging is preferred over tubes. Evaluate power consumption differences between standard and low-power variants within the ISO776x family to match system energy constraints.

Part Context

This part belongs to the ISO7761 series of high-speed digital isolators. It shares functional similarities with ISO7760 and ISO7762 models but differs in channel count and configuration. The QDBB suffix denotes the SSOP package type, while QQ1 specifies the tube packaging format used for manual assembly or specific manufacturing processes.

Replacement Considerations

ISO7761QDBQRQ1 serves as a direct substitute offering identical electrical specifications but in tape-and-reel packaging instead of tubes. Verify pinout compatibility and thermal characteristics before swapping packaging types in existing designs.
