Procurement Notes

Verify the specific suffix 'CTSOCT' against the manufacturer's official documentation to confirm tape-and-reel packaging and lead-free composition. Ensure the component matches the required industrial temperature grade and package dimensions. Cross-reference the ordering part number with the latest datasheet revision to avoid discrepancies in pinout or electrical characteristics during procurement.

Selection Notes

Select this component when an octal register with high-drive three-state outputs is required. It is suitable for designs needing TTL-compatible inputs and robust performance across industrial temperatures. Consider the SOIC-20 package constraints and power supply requirements. Evaluate if the 10 ns propagation delay meets the timing specifications of the target application circuit compared to faster alternatives.

Part Context

This part is part of the CY74FCT574T family, which includes variants with different packaging options such as tube or reel configurations. The base model defines the core logical function, while suffixes indicate specific manufacturing details like environmental compliance and shipping format. It serves as a standard solution for octal data storage in CMOS-based logic systems.

Replacement Considerations

Direct substitutes include CY74FCT574TSOC and CY74FCT574CTSOC. Verify that alternative part numbers maintain identical pinouts, electrical specifications, and package dimensions before implementation.
