Overview
The IDT 74FCT574PBCTSO is an octal D-type register featuring three-state outputs, designed for high-speed digital data storage and transfer applications. Manufactured by Integrated Device Technology Inc, this component belongs to the FCT logic family, ensuring compatibility with standard TTL input levels while providing enhanced drive capabilities. The device incorporates eight independent D-type flip-flops with positive-edge triggering, allowing for precise synchronization of data signals within complex circuit architectures.
Feature Summary
- Octal configuration providing eight independent D-type flip-flops for parallel data handling
- Three-state output capability enabling efficient bus sharing and system control
- Positive-edge triggering mechanism for accurate data synchronization
- TTL-compatible input structure ensuring broad interface compatibility
Applications
- High-speed data buffering in communication systems
- Parallel-to-serial data conversion interfaces
- Microprocessor memory address latching circuits
- Digital signal processing data path synchronization
Procurement Notes
Verify the specific suffix PBCTSO against official IDT documentation to confirm package type and tape/reel specifications. Ensure the source document explicitly identifies the manufacturer as Integrated Device Technology Inc or its successor entities. Cross-reference the part number with current product lifecycle status to confirm availability and compliance requirements before procurement.
Selection Notes
Select this component when an octal register with tri-state outputs is required for high-speed data management. The FCT series offers superior performance compared to standard 74LS logic families. Consider the QSOP-20 package dimensions and thermal characteristics during PCB layout. Verify voltage supply requirements match the system design specifications for reliable operation.
Part Context
This part belongs to the 74FCT logic family, a high-performance CMOS technology developed for fast digital applications. The 74FCT574 variant specifically provides octal storage functionality. IDT, now part of Renesas Electronics, historically produced these components for industrial and commercial electronic systems requiring reliable data retention and transfer capabilities.
Replacement Considerations
Cross-reference with Texas Instruments CY74FCT574CTQCT for functional equivalence in octal D-register applications. Verify pinout compatibility and electrical parameters against official datasheets before substitution. Ensure package differences do not impact mechanical fit or thermal performance in the target assembly.
