SN74LVC574AGQNR

Flip Flops Overview

The SN74LVC574AGQNR is an automotive-grade octal edge-triggered D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and supports clock frequencies up to 150 MHz. The device features non-inverting logic with CMOS and TTL input compatibility, delivering output currents of ±24 mA. Propagation delay is typically 7.8 ns. It is housed in a 20-pin TSSOP package and rated for operation from -40°C to +125°C.

Flip Flops Feature Summary

• Automotive-grade reliability compliant with AEC-Q100 standards
• Octal configuration providing eight independent D-type flip-flops
• High-speed performance supporting 150 MHz clock frequencies
• Wide operating temperature range suitable for harsh environments

Flip Flops Applications

• Automotive electronic control units requiring robust data storage
• Industrial systems needing high-reliability logic components
• Consumer electronics utilizing low-voltage logic interfaces

Flip Flops Procurement Notes

Verify the specific suffix 'GQNR' confirms automotive qualification and tape-and-reel packaging. Ensure the source document explicitly states AEC-Q100 compliance for this exact part number. Confirm the manufacturer is Texas Instruments and the package type matches the required PCB footprint. Cross-reference the datasheet revision date to ensure current specifications.

Flip Flops Selection Notes

Select this component when automotive certification is mandatory for octal flip-flop applications. It is suitable for designs requiring 3-state outputs and wide voltage tolerance. Consider the TSSOP-20 package constraints and thermal characteristics. Verify that the 150 MHz speed meets system timing requirements compared to standard commercial variants.

Flip Flops Part Context

This part belongs to the SN74LVC574A family of octal edge-triggered D-type flip-flops. The 'AQ' designation indicates automotive qualification, while 'GQNR' specifies the green plastic small-outline package with lead finish and reel packing. It complements other LVC series devices offering similar functionality with varying package or grade options.

Flip Flops Replacement Considerations

SN74LVC574ADBR is a commercial-grade alternative with identical electrical specifications but lacks automotive qualification. SN74LVC574APWG4 offers similar performance in a tube-packaged format. Verify if automotive grading is strictly required before substituting with commercial versions.
