Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as documentation indicates non-compliance in some records. Ensure the specific suffix matches project requirements for package dimensions and thermal characteristics. Cross-reference datasheet revisions to validate performance parameters against current design specifications.
Selection Notes
Select this component for designs requiring octal latching with tri-state buffering in a compact surface-mount format. Compare propagation delays and drive strengths against alternative FCT series devices. Consider the operating temperature range limits when evaluating environmental constraints. Verify pinout compatibility with existing PCB layouts before integration.
Part Context
This part belongs to the 74FCT374 series of octal D registers manufactured by Integrated Device Technology. It serves as a digital logic component for storing and transferring parallel data. The device is part of the broader FAST CMOS family, offering speed advantages over standard TTL while maintaining compatible logic levels.
Replacement Considerations
Texas Instruments CY74FCT374ATQCT and CY74FCT374TQCT are documented similar replacements. Renesas IDT74FCT374ATPY8 is also listed as a substitute option.
