CY74FCT374ATSOCT

Overview

The CY74FCT374ATSOCT is an octal D-type flip-flop register with 3-state outputs manufactured by Texas Instruments. It belongs to the FCT logic series and utilizes a SOIC-20 surface-mount package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a wide operating temperature range from -40°C to +85°C. Key electrical parameters include a propagation delay of 6.5 ns, high-level output current of -32 mA, and low-level output current of 64 mA. It features TTL input levels and non-inverting polarity.

Feature Summary

• Octal D-type configuration providing eight independent data storage elements within a single integrated circuit.
• Three-state outputs enable direct connection to bus systems without requiring external buffer drivers.
• TTL-compatible input thresholds ensure reliable signal recognition across standard logic families.

Applications

• Parallel-to-serial data conversion in communication interfaces
• Temporary storage for address or data buses in microprocessor systems
• Register stages in digital control logic circuits

Procurement Notes

Verify the specific suffix 'OC' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications and moisture sensitivity level ratings. Ensure that the SOIC-20 footprint matches the target PCB design constraints. Cross-reference the RoHS compliance status with the latest environmental declarations provided by Texas Instruments prior to finalizing procurement orders.

Selection Notes

Select this component when an octal register with high drive capability and bus-compatible outputs is required. The FCT series offers faster switching speeds compared to standard CMOS alternatives while maintaining low power consumption. Consider the 6.5 ns propagation delay for timing-critical applications and verify that the 3-state output architecture aligns with the system's bus topology requirements.

Part Context

This part is a member of the CY74FCT374T family, which includes various packaging options such as tube and reel configurations. The ATSOCT designation specifically indicates the SOIC-20 package type with industrial temperature rating and reel packaging. Other variants in the series may differ in pin count, package style, or thermal characteristics while retaining identical logical functionality.

Replacement Considerations

Direct substitutes within the same family include CY74FCT374ATSOC, which shares identical electrical specifications but differs in packaging format. Verify compatibility regarding lead finish and reflow soldering profiles when transitioning between different package types within the 74FCT374 product line.

FAQ

What is the maximum low-level output current capability?

The device provides a low-level output current of 64 mA, allowing it to drive heavy capacitive loads directly.

Does the device support bidirectional data transfer?

No, the CY74FCT374ATSOCT is a unidirectional register designed for data capture and storage, not bidirectional transmission.
