Procurement Notes

Verify the specific manufacturer source when sourcing this component, as multiple vendors including Fairchild and Texas Instruments produce equivalent part numbers. Confirm that the QSOP package variant matches the required footprint dimensions. Check RoHS compliance status against project requirements. Ensure the lead time aligns with production schedules due to potential availability variations across different distributors.

Selection Notes

Select this component for designs requiring low-voltage operation between 2 V and 3.6 V. The LVQ series provides high-speed performance suitable for demanding digital applications. Consider the 20-QSOP package for space-constrained surface mount layouts. Evaluate the ±12 mA output drive capability against load requirements. Compare propagation delay specifications with timing constraints to ensure signal integrity.

Part Context

This component belongs to the 74LVQ family of low-voltage CMOS logic devices. The LVQ series is designed for high-speed applications while maintaining low power consumption. It complements other logic families like HC and HCT by offering faster switching speeds at lower supply voltages. The octal flip-flop configuration is standard for managing parallel data streams in digital systems.

Replacement Considerations

Equivalent parts include 74LVQ273 from Fairchild Semiconductor and Texas Instruments. Verify pin compatibility and electrical characteristics before substitution. Ensure the replacement maintains the same 20-QSOP package outline.
