SN74AHC574DGVR

Flip Flops Overview

The SN74AHC574DGVR is an octal edge-triggered D-type flip-flop with three-state outputs manufactured by Texas Instruments. It belongs to the AHC logic series and utilizes a TVSOP-20 surface-mount package. The device operates within a supply voltage range of 2 V to 5.5 V, supporting CMOS input types. Key electrical parameters include a maximum propagation delay of 16.7 ns, high-level output current of -8 mA, and low-level output current of 8 mA. It functions as a non-inverting buffer suitable for bus-oriented applications.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single integrated circuit
• Three-state outputs designed for efficient bus-driven architectures and data line management
• CMOS input compatibility ensuring low input current and broad signal integration capabilities

Flip Flops Applications

• Buffer registers for temporary data storage and signal conditioning
• I/O ports for interfacing microcontrollers with peripheral devices
• Bidirectional bus drivers for managing data flow across system buses
• Working registers for holding state information in digital logic circuits

Flip Flops Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and green manufacturing status as per Texas Instruments documentation. Confirm the TVSOP-20 package dimensions match the target PCB footprint requirements. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the datasheet revision history for any updates to electrical characteristics or recommended operating conditions before finalizing component selection.

Flip Flops Selection Notes

Select this component when an octal register with tri-state capability is required for bus systems. The AHC series offers faster switching speeds compared to standard HC logic while maintaining CMOS compatibility. Consider the 2 V to 5.5 V supply range for flexibility in mixed-voltage environments. The TVSOP-20 package provides a compact solution for space-constrained designs requiring surface-mount technology.

Flip Flops Part Context

This part is a member of the Texas Instruments SN74AHC574 family, which includes variants with different packages such as SOIC and SSOP. The DGVR suffix specifically denotes the TVSOP-20 package type with reel packaging. It serves as a direct replacement for older octal flip-flop designs requiring higher speed and lower power consumption than legacy TTL or standard CMOS counterparts.

Flip Flops Replacement Considerations

SN74AHC574DWR is a compatible alternative featuring the same logical functionality but housed in a 20-SOIC package instead of TVSOP-20. Designers must verify pin-to-pin compatibility and mechanical footprint differences when substituting between package types. Other family members like SN74AHCT574 offer TTL-compatible inputs if voltage level shifting is required.
