Translators, Level Shifters Procurement Notes

Verify the specific suffix BQ corresponds to the DHVQFN20 (SOT764-1) package variant. Confirm that the ordered component matches the Rev 2.1 datasheet dated 25 July 2024. Ensure design compliance with the recommended operating conditions, specifically the input voltage limits and temperature range specifications provided in the official Nexperia documentation.

Translators, Level Shifters Selection Notes

Select this component when flexible per-channel voltage translation is required for open-drain and push-pull applications. It is suitable for designs needing high-speed data rates up to 100 MHz with minimal system effort due to the absence of a direction pin. Consider the DHVQFN20 package constraints and thermal dissipation requirements for space-constrained PCB layouts.

Translators, Level Shifters Part Context

The LSF0108BQX belongs to the LSF0108 family of 8-bit bidirectional multi-voltage level translators manufactured by Nexperia. This family provides flexible voltage translation capabilities across multiple channels, allowing different voltage levels on each channel. The BQ suffix specifically denotes the DHVQFN20 package version, distinguishing it from other package options like TSSOP20.

Translators, Level Shifters Replacement Considerations

LSF0108PW is the TSSOP20 package equivalent within the same functional family.
