CY74FCT574ATSOCT

Overview

The CY74FCT574ATSOCT is an octal edge-triggered D-type flip-flop with three-state outputs manufactured by Texas Instruments. It belongs to the FCT logic series and features a non-inverting polarity. The device operates within a supply voltage range of 4.75 V to 5.25 V. It exhibits a propagation delay of 10 ns, with high-level output current capability of -32 mA and low-level output current of 64 mA. The component is housed in a 20-SOIC package and supports surface mount installation. It functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Octal edge-triggered D-type flip-flop architecture with three-state outputs
• Compatible TTL input levels for direct interface with standard logic systems
• High drive strength supporting significant load currents on both output states

Applications

• Parallel data storage and buffering in digital systems
• Interface bridging between microprocessors and peripheral devices
• Register implementation in high-speed data acquisition circuits

Procurement Notes

Verify the specific suffix 'TSOC' against official Texas Instruments documentation to confirm the tape-and-reel packaging configuration and moisture sensitivity classification. Ensure that the ordering part number matches the exact electrical specifications and package dimensions required for the target PCB layout. Cross-reference the manufacturer's latest datasheet to validate any potential changes in RoHS compliance or recommended soldering profiles prior to procurement.

Selection Notes

Select this component when an octal register with three-state output control is required for bus-oriented applications. The FCT series offers CMOS speed with TTL compatibility, making it suitable for systems needing fast switching without level shifting. Consider the 20-SOIC package constraints and thermal performance limits when designing for the specified industrial temperature range. Evaluate the 10 ns propagation delay against system timing requirements to ensure signal integrity.

Part Context

This part is a member of the CY74FCT574T family, which includes variants with different packaging options such as SOIC tubes and QSOP reels. The 'A' designation typically indicates the commercial temperature grade, while 'TSOC' specifies the reel packaging format. It shares functional similarities with other octal registers in the FCT lineup but differs in physical form factor and handling characteristics compared to tube-packaged equivalents like the SOC variant.

Replacement Considerations

CY74FCT574ATQCT provides equivalent functionality in a QSOP-20 reel package. CY74FCT574ATSOC offers the same electrical performance in a SOIC-20 tube package.
