Procurement Notes

This component has been officially discontinued by NXP Semiconductors as confirmed by discontinuation notifications dated March 2015. Manufacturers have ceased production, and the part is no longer available for new orders. Verification of current stock availability through authorized distributors is essential before design finalization due to the obsolete status.

Selection Notes

Designers must evaluate alternative components immediately given the discontinuation status. Selection should focus on pin-compatible replacements or functional equivalents from other manufacturers that maintain the 74LVT series specifications. Verify that substitute parts offer identical voltage ranges, package dimensions, and electrical characteristics to ensure seamless integration into existing hardware architectures.

Part Context

The 74LV/LVT family represents low-voltage CMOS logic designed for high-speed digital applications. This specific model belongs to the LVT subset, optimized for operation at lower supply voltages while maintaining compatibility with standard logic levels. The TSSOP packaging facilitates compact circuit board layouts for modern electronic devices requiring dense interconnects.

Replacement Considerations

Publicly documented substitutes include MC74LVX574DTR2G and SN74LV574ADBR. These alternatives provide similar functionality but may differ in output polarity or specific electrical parameters. Engineers must verify compatibility with existing circuit designs when transitioning to these replacement part numbers.
