SN74HCT574DBR

Flip Flops Overview

The SN74HCT574DBR is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It features eight independent D-type flip-flops with tri-state outputs, designed for bus-driven applications. The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a 20-pin SSOP package. It exhibits a typical propagation delay of 22 ns at 5 V and supports low power consumption with a maximum ICC of 80 µA. The outputs are non-inverting and can directly drive bus lines or up to 15 LSTTL loads.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops for parallel data storage
• Tri-state outputs enable direct connection to system buses without external buffers
• TTL-compatible inputs ensure compatibility with standard logic families
• Low static power consumption suitable for battery-operated or energy-efficient designs

Flip Flops Applications

• Buffer registers for temporary data storage in digital systems
• I/O ports for interfacing microprocessors with peripheral devices
• Bidirectional bus drivers for managing data flow across shared lines
• Working registers within arithmetic logic units or control circuits

Flip Flops Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SSOP-20 package and reel packaging format required for your assembly process. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input voltage levels match TTL standards to guarantee proper logic threshold recognition during operation.

Flip Flops Selection Notes

Select this component when an octal register with tri-state capability is needed for bus-oriented architectures. The HCT series ensures compatibility with 5 V TTL logic levels, making it suitable for legacy system upgrades. Consider the SSOP package dimensions against available PCB real estate constraints before finalizing the design.

Flip Flops Part Context

This part belongs to the SN74HCT574 family of octal D-type flip-flops. It shares functional similarities with other variants like SN74HCT574NSR but differs in physical packaging. The DBR designation specifically indicates surface-mount technology in a shrink small-outline package, distinguishing it from wider SOIC or TSSOP alternatives within the same logical family.

Flip Flops Replacement Considerations

SN74HCT574NSR offers identical electrical functionality in a 20-SOIC package. SN74HCT574PWR provides the same logic in a 20-TSSOP footprint. Verify pinout compatibility and thermal characteristics when substituting these packages.
