Procurement Notes
This component is officially obsolete and no longer manufactured by STMicroelectronics. Procurement must focus on verified direct substitutes such as the SN74LVC374ADW or Nexperia 74LVC374AD,118. Verify that replacement parts match the original pinout, electrical characteristics, and package dimensions to ensure circuit compatibility without redesign.
Selection Notes
Select this part for designs requiring octal storage with tri-state outputs in low-voltage logic families. Ensure the application environment stays within the specified -55°C to 125°C range. Consider input capacitance of 4pF for signal integrity analysis. Due to obsolescence, prioritize alternative sources only if they provide identical functional specifications and mechanical footprint.
Part Context
Part of the 74LVC series, designed for low-voltage CMOS applications. The 74LVC374A variant provides enhanced speed compared to standard LVC devices. Manufactured by STMicroelectronics, it utilizes surface-mount technology in a 20-SOIC package. The series is known for rail-to-rail swing and compatibility with various logic families.
Replacement Considerations
Direct substitute part numbers include SN74LVC374ADW (Texas Instruments) and 74LVC374AD,118 (Nexperia). Verify pin compatibility and electrical parameters before substitution.
