CY74FCT2574TSOCTE4

Overview

The CY74FCT2574TSOCTE4 is an octal D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It belongs to the FCT logic series, designed for high-speed and low-power applications. The device features a 20-pin SOIC package and operates within a supply voltage range of 4.75 V to 5.25 V. It supports TTL input levels and provides non-inverting data transfer triggered on the positive edge of the clock signal. The component is rated for operation between -40°C and +85°C.

Feature Summary

• Octal D-type flip-flop architecture with 3-state output capability
• High-speed, low-power CMOS technology implementation
• TTL-compatible input levels for direct interface integration

Applications

• Parallel-to-serial data conversion circuits
• Buffering and latching in digital systems
• I/O port expansion modules

Procurement Notes

Verify the specific suffix E4 indicates lead-free compliance and RoHS status against current manufacturer documentation. Confirm the SOIC-20 package type matches the target PCB footprint requirements. Ensure the operating temperature range aligns with the environmental conditions of the intended deployment scenario before finalizing procurement.

Selection Notes

Select this component when an octal register with tri-state outputs is required for high-speed data handling. It serves as a suitable alternative to standard FCT logic devices where TTL compatibility is necessary. Consider the 20-pin SOIC form factor for surface-mount assembly constraints and verify power supply stability within the specified 4.75 V to 5.25 V window.

Part Context

This part is part of the CY74FCT2574T family, which includes variants like CY74FCT2574TSOC. It shares functional similarities with other octal registers in the FCT series but is distinguished by its specific package and compliance markings. The device complements Texas Instruments' portfolio of high-performance logic ICs designed for complex digital system architectures.

Replacement Considerations

CY74FCT2574TSOC is a functionally equivalent variant within the same product line.
