ISO7142CCQDBQQ1

Overview

The ISO7142CCQDBQQ1 is a general-purpose digital isolator from Texas Instruments, designed for automotive applications. It features four independent channels with two forward and two reverse paths, housed in a 16-pin SSOP package. The device supports data rates up to 50 Mbps and provides an isolation rating of 2500 Vrms. It operates within a supply voltage range of 2.7 V to 5 V and maintains functionality across an extended temperature range of -55°C to +125°C.

Feature Summary

• Automotive qualified to AEC-Q100 standards for robust reliability
• Capacitive coupling technology ensures high common-mode transient immunity
• Low-power quad-channel architecture minimizes energy consumption

Applications

• Automotive engine control units
• Body electronics systems
• Industrial communication interfaces

Procurement Notes

Verify the specific suffix QDBQQ1 to confirm automotive qualification and package type. Ensure compatibility with your system's voltage levels and thermal requirements. Cross-reference the datasheet for pinout configurations and electrical characteristics before integration. Confirm that the component meets all relevant safety and regulatory standards for your target market.

Selection Notes

Select this component when automotive-grade durability and low power consumption are critical. It is suitable for designs requiring four isolated channels with moderate data speeds. Consider the SSOP package size for space-constrained PCB layouts. Evaluate the 2500 Vrms isolation barrier against your system's safety requirements.

Part Context

This part belongs to the ISO7142 family of digital isolators, which are optimized for low power and small footprint. The ISO7142 series is widely used in industrial and automotive sectors where reliable signal transmission across isolation barriers is essential. The QDBQQ1 variant specifically targets automotive environments with enhanced temperature and reliability specifications.

Replacement Considerations

ISO7142CCDBQR is a non-automotive equivalent with similar electrical characteristics but lacks AEC-Q100 qualification.
