SN74LVTH574RGYR

Flip Flops Overview

The SN74LVTH574RGYR is an octal edge-triggered D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It belongs to the LVTH logic series and operates within a supply voltage range of 2.7 V to 3.6 V. The device features a propagation delay of 3 ns, with high-level output current capability of -32 mA and low-level output current of 64 mA. It utilizes a VQFN-20 package for surface-mount installation and supports non-inverting TTL input types across eight circuits.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single integrated circuit
• 3-state outputs allowing direct connection to bus lines without additional interface hardware
• Edge-triggered data storage synchronized with positive clock transitions for precise timing control
• TTL-compatible inputs ensuring interoperability with standard digital logic families

Flip Flops Applications

• Parallel-to-serial data conversion in communication interfaces
• Bus-oriented memory register implementations
• High-speed data latching and buffering applications
• Clock domain crossing synchronization circuits

Flip Flops Procurement Notes

Verify the specific suffix RGYR corresponds to the VQFN-20 package variant when sourcing. Confirm moisture sensitivity level requirements for reflow soldering profiles. Ensure the ordering quantity aligns with manufacturer reel specifications. Cross-reference the active status with official Texas Instruments documentation to avoid obsolete stock.

Flip Flops Selection Notes

Select this component when a 3.3 V logic family with fast switching speeds is required. The LVTH series offers superior performance compared to standard LV devices while maintaining compatibility. Consider the VQFN-20 footprint constraints during PCB layout. Evaluate thermal dissipation needs given the compact package size and high drive currents available.

Flip Flops Part Context

This part is part of the SN74LVTH574 family, which includes variants with different packaging options such as TSSOP, SSOP, and SOIC. All variants share identical electrical characteristics and logical functionality. The RG suffix specifically denotes the VQFN package type, distinguishing it from other physical form factors within the same functional group.

Flip Flops Replacement Considerations

SN74LVTH574PW (TSSOP-20), SN74LVTH574DBR (SSOP-20), SN74LVTH574DW (SOIC-20). These parts share identical electrical specifications but differ in physical package dimensions.
