SN74HCT374DWR

Flip Flops Overview

The SN74HCT374DWR is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments, housed in a 20-pin SOIC package. It features tri-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device exhibits a propagation delay of 46 ns, with high-level output current of -6 mA and low-level output current of 6 mA. It supports TTL input levels and functions across an extended temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops for parallel data storage
• Tri-state outputs enable direct connection to bus systems without external drivers
• Edge-triggered operation ensures data capture on the positive clock transition
• TTL-compatible inputs allow seamless integration with standard logic families

Flip Flops Applications

• Parallel-to-serial conversion circuits
• Buffering and latching digital signals
• Bus-oriented memory register designs
• Data acquisition system interfaces

Flip Flops Procurement Notes

Verify that the component matches the exact SN74HCT374DWR designation to ensure correct HCT logic family compatibility. Confirm the SOIC-20 package type aligns with PCB footprint requirements. Check RoHS compliance status against specific project regulations. Validate operating temperature range specifications for environmental suitability. Ensure datasheet revisions match design documentation requirements.

Flip Flops Selection Notes

Select this part when TTL-compatible inputs are required alongside tri-state bus capabilities. The HCT series offers speed comparable to LS logic while maintaining CMOS power efficiency. Consider the 46 ns propagation delay for timing constraints. Evaluate the 20-pin SOIC package for surface-mount assembly needs. Compare against HC or LVTH variants if voltage ranges or drive strengths differ significantly.

Flip Flops Part Context

This component belongs to the SN74HCT374 family of octal flip-flops. It shares functional similarities with the SN74HCT373 but differs in triggering mechanism. The DWR suffix indicates tape-and-reel packaging for automated assembly. It complements other HCT series devices like the SN74HCT595 for comprehensive digital logic solutions.

Flip Flops Replacement Considerations

SN74HCT374DW serves as a non-reel alternative with identical electrical characteristics.
