Procurement Notes

Verify component authenticity through authorized distributors due to discontinued status. Confirm package integrity and pin alignment against the 20-LSSOP specification. Check datasheet revisions for any updates regarding electrical limits or thermal characteristics before integration into final designs.

Selection Notes

Select this component for applications requiring octal storage with tri-state control under low voltage conditions. Ensure the design accommodates the 2V minimum supply requirement. Consider the 75 MHz clock limit for timing analysis. Verify that the LSSOP package fits the PCB footprint constraints compared to standard SOIC options.

Part Context

This part belongs to the 74LVQ series, designed for low-voltage operations between 2V and 3.6V. It complements other LVQ devices like the 74LVQ174 by offering octal rather than hex configurations. The series targets portable and battery-powered applications where power efficiency and speed are critical performance factors.

Replacement Considerations

Public confirmed substitutes include MC74LVX374DTR2G and SN74LV374ADBR. Verify pin compatibility and electrical specifications against these alternatives. Note that package differences may require adapter solutions or PCB redesigns during transition.
