Procurement Notes

Verify the specific suffix KSRQ1 against official Texas Instruments documentation to confirm the exact package variant and automotive qualification status. Ensure compatibility with AEC-Q100 standards if required for your specific application environment. Cross-reference the datasheet for precise pinout configurations and electrical characteristics relevant to the VQFN-20 package type before finalizing procurement decisions.

Selection Notes

Select this component when designing automotive circuits that require robust bidirectional translation between multiple voltage domains. Consider the 8-channel capacity and high-speed performance metrics relative to your interface requirements. Evaluate the thermal performance and package size constraints associated with the VQFN-20 form factor to ensure adequate space and heat dissipation within the target assembly design.

Part Context

This part belongs to the TXS0108E series of voltage-level translators from Texas Instruments. It is specifically designated for automotive use, indicated by the Q1 suffix in the ordering code. The series offers various package options including VQFN and VSSOP, catering to different PCB layout needs while maintaining consistent electrical performance and automotive reliability standards.

Replacement Considerations

TXS0108EQDGSRQ1 is a verified alternative within the same family, offering identical electrical specifications but utilizing a VSSOP-20 package instead of VQFN-20. Verify footprint compatibility and thermal requirements when substituting packages.
