ISO7760QDWQ1

Overview

The ISO7760QDWQ1 is an automotive-grade, high-speed, reinforced six-channel digital isolator manufactured by Texas Instruments. It utilizes capacitive coupling technology to provide galvanic 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 Mbps per channel. It features a common-mode transient immunity (CMTI) of 85 kV/µs and offers propagation delays of 17 ns maximum. The component is housed in a 16-pin SOIC package with a 7.50 mm width and is qualified under AEC-Q100 standards for operation between -40°C and +125°C.

Feature Summary

• Provides reinforced insulation for six independent signal channels using capacitive coupling technology.
• Delivers high common-mode transient immunity of 85 kV/µs to ensure reliable operation in noisy environments.
• Supports high-speed data transmission with a maximum rate of 100 Mbps per channel.
• Designed for automotive applications with AEC-Q100 qualification and extended temperature range capability.

Applications

• Automotive isolated communication interfaces
• Industrial control systems requiring robust EMC performance
• Inverter gate drive circuits
• Motor control applications

Procurement Notes

Verify the specific suffix 'QDWQ1' to confirm the automotive grade, 16-SOIC package, and tube packaging configuration. Ensure compatibility with the target system's voltage levels and isolation requirements. Cross-reference the manufacturer part number against official Texas Instruments documentation to avoid counterfeit components. Confirm that the AEC-Q100 qualification meets the specific reliability standards required for the intended automotive application.

Selection Notes

Select this component when six isolated channels are required for high-speed data transmission in automotive or industrial settings. Consider the 100 Mbps data rate and 85 kV/µs CMTI for noise-sensitive applications. Evaluate the 16-SOIC footprint against available PCB space. Compare power consumption and propagation delay specifications against other isolators if timing precision is critical. Ensure the operating temperature range aligns with the environmental conditions of the deployment site.

Part Context

The ISO7760Q series belongs to Texas Instruments' family of automotive digital isolators designed for robust electromagnetic compatibility. These devices replace traditional magnetic couplers in many applications due to their smaller size and lower power consumption. The ISO7760QDWQ1 specifically addresses the need for multi-channel isolation in complex automotive networks and motor drives, offering a compact solution within the SOIC-16 package format.

Replacement Considerations

ISO7760QDWRQ1 is a recommended manufacturer replacement with identical electrical characteristics but different packaging (reel vs. tube). Verify pinout compatibility before substitution.
