Flip Flops Procurement Notes

Verify the specific ordering suffix against the official datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status as required by project standards. Check for obsolescence notices or product change notifications from onsemi prior to finalizing procurement plans.

Flip Flops Selection Notes

Select this component for designs requiring 8-bit storage with low voltage compatibility. Ensure the system supply voltage remains within the 2 V to 3.6 V range. Verify that the 20-SOEIAJ footprint matches the target PCB layout. Consider the 9.5 ns propagation delay when determining maximum clock speeds for synchronous circuits.

Flip Flops Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices. It serves as an octal flip-flop variant within the broader 74xx logic ecosystem. The device is designed to bridge 5 V and 3.3 V systems while maintaining low static power dissipation typical of LCX technology.

Flip Flops Replacement Considerations

Direct substitutes include MC74LCX574MELG and MC74LCX574DWR2G. Cross-manufacturer equivalents such as SN74LVC574ADBR may be considered if electrical characteristics align with system requirements.
