Flip Flops Procurement Notes

Verify the specific suffix 'DBR' corresponds to the TVSOP-20 package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact manufacturer designation to avoid pinout or electrical specification mismatches during procurement.

Flip Flops Selection Notes

Select this component when an octal storage element with three-state outputs is required for wide voltage operation. The AHC series offers faster switching speeds compared to standard HC logic while maintaining CMOS compatibility. Consider the TVSOP-20 package constraints regarding thermal dissipation and board space availability for surface-mount implementation.

Flip Flops Part Context

This device is part of the SN74AHC574 family of octal D-type flip-flops. It shares functional similarities with other variants like SN74AHC574DWR but differs in package type. The AHC series represents advanced high-speed CMOS technology designed for low power consumption and high noise immunity in digital logic applications.

Flip Flops Replacement Considerations

SN74AHC574DR is a compatible alternative with identical electrical specifications but utilizes a SOIC-20 package instead of TVSOP-20. Verify pinout compatibility and physical footprint differences before substitution.
