ISO7231CQDWRQ1

Digital Isolators Overview

The ISO7231CQDWRQ1 is a triple-channel digital isolator from Texas Instruments, designed for high-speed data transmission in automotive applications. It features capacitive coupling technology and operates within a supply voltage range of 3.15V to 5.5V. The device supports a data rate of 25Mbps with a maximum propagation delay of 45ns. It provides an isolation voltage of 4000Vpk and a common-mode transient immunity (CMTI) of 25kV/µs. Packaged in a 16-SOIC format, it functions bidirectionally across channels with a 2/1 input-output configuration.

Digital Isolators Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and temperature grade. Confirm AEC-Q100 certification status if automotive compliance is mandatory. Check datasheet revisions for any updates to electrical characteristics or pin configurations before finalizing designs.

Digital Isolators Selection Notes

Select this component when triple-channel isolation is required at 25Mbps speeds. Ensure the 4000Vpk isolation rating meets system safety requirements. Consider the 16-SOIC package dimensions for PCB layout constraints. Verify that the 3.15V to 5.5V supply range aligns with the target logic levels.

Digital Isolators Part Context

Part of the ISO723x-Q1 family of high-speed digital isolators. Designed specifically for automotive applications where reliability and noise immunity are critical. Offers multiple channel configurations to reduce bill of materials count compared to single-channel alternatives.

Digital Isolators Replacement Considerations

Check ISO7231CDWR for non-automotive equivalents. Verify ISO7231CQDWQ1 for tube packaging options. Ensure substitute parts maintain AEC-Q100 qualification and identical pinout compatibility.
