CY74FCT2574ATSOC

Overview

The CY74FCT2574ATSOC is an octal D-type register with 3-state outputs manufactured by Texas Instruments. It belongs to the FCT logic series and operates within a supply voltage range of 4.75 V to 5.25 V. The device features a propagation delay of 6.5 ns, with high-level output current capability of -15 mA and low-level output current of 12 mA. It is housed in a 20-pin SOIC package and supports single-ended TTL input levels. The component functions as a non-inverting buffer suitable for bus transmission applications.

Feature Summary

• Octal D-type register architecture providing eight independent data storage channels
• Three-state output configuration enabling efficient bus line driving and isolation
• TTL-compatible input thresholds ensuring direct interface with standard logic systems

Applications

• Parallel data buffering in microprocessor-based systems
• Bus transceiver circuits requiring isolated signal paths
• Memory address latching in embedded controller designs

Procurement Notes

Verify the specific suffix designation against official Texas Instruments documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints and voltage requirements before integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when designing systems requiring parallel data storage with high-speed bus interfacing capabilities. Consider the 6.5 ns propagation delay for timing constraints and verify that the 20-pin SOIC package fits the available board space. Confirm that the 3-state outputs align with the system's bus arbitration requirements.

Part Context

This device is part of the broader CY74FCT family of fast CMOS logic products designed for high-performance digital applications. It serves as a specialized variant within the octal register category, offering distinct electrical characteristics compared to other members of the series such as the CY74FCT374 or CY74FCT2573.
