CY74FCT374TSOCT

Overview

The CY74FCT374TSOCT is an octal D-type flip-flop register manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting D inputs and three-state outputs, designed for high-speed digital applications. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports TTL input levels. Packaged in a 20-pin SOIC surface-mount format, it ensures reliable performance across an industrial temperature range from -40°C to +85°C. Key electrical specifications include a propagation delay of 10 ns at 5 V with 50 pF load, a low-level output current capability of 64 mA, and a high-level output current of -32 mA.

Feature Summary

• Octal D-type flip-flop configuration with registered data storage capabilities
• Three-state outputs enabling direct bus interface connections without external buffers
• TTL-compatible input thresholds ensuring interoperability with standard logic families

Applications

• Parallel-to-serial data conversion circuits
• High-speed buffering between microprocessors and memory systems
• Clocked data registration in communication interfaces

Procurement Notes

Verify the specific suffix 'TSOCT' corresponds to the tape-and-reel packaging variant rather than tube packaging when sourcing components. Confirm that the ordering part number matches the required package type and reel quantity specifications. Ensure compliance with RoHS directives as indicated in official documentation. Cross-reference the manufacturer's latest datasheet for any updates regarding mechanical dimensions or recommended soldering profiles prior to procurement.

Selection Notes

Select this component for designs requiring octal data latching with high drive strength and fast switching speeds. The FCT series offers superior performance compared to standard 74F logic while maintaining pin compatibility. Consider the 20-pin SOIC package constraints for PCB layout. Evaluate the 10 ns propagation delay against system timing requirements. Verify that the 5V operating voltage aligns with the target power supply architecture.

Part Context

This device is part of the CY74FCT374T family, which includes variants such as CY74FCT374TSOC (tube) and CY74FCT374ATPC (PDIP). The TSOC designation typically indicates a standard tube package, whereas the additional 'T' in TSOCT often signifies tape and reel packaging for automated assembly. All variants share identical electrical characteristics and logical functionality, differing primarily in shipping and handling formats.

Replacement Considerations

CY74FCT374TSOC: Identical electrical specifications; differs only in packaging format (tube vs. tape and reel).
