Procurement Notes

This component is officially classified as obsolete and no longer manufactured by the producer. Verification of availability requires checking secondary market channels or authorized distributors for remaining stock. Engineers must confirm that any sourced units are genuine and match the original datasheet specifications before integration into new designs.

Selection Notes

Designers should evaluate alternative components from the same logic family or compatible manufacturers due to the discontinued status of this specific part number. Selection criteria must include matching pinout compatibility, electrical parameters such as propagation delay and drive current, and package dimensions to ensure seamless replacement without circuit board redesign.

Part Context

The 74LV574DB,118 belongs to the 74LV series of low-voltage CMOS logic devices produced by NXP Semiconductors. This series is characterized by operation down to 1V while maintaining TTL-compatible input levels. The DB variant specifically denotes the SSOP-20 surface-mount package configuration used in compact electronic assemblies.
