Flip Flops Procurement Notes

Verify the specific ordering suffix matches the required package variant and tape-and-reel specifications. Confirm RoHS compliance status aligns with project environmental requirements. Check the latest product change notification for any manufacturing site or material updates. Ensure the supplier source is authorized to guarantee component authenticity and traceability throughout the supply chain.

Flip Flops Selection Notes

Select this component when designing 5V logic circuits requiring high-speed data retention with minimal propagation delay. The 24 mA output current capability supports driving moderate capacitive loads directly. Consider the TSSOP-20 footprint constraints during PCB layout planning. Verify that the operating temperature range meets the specific environmental conditions of the target application environment.

Flip Flops Part Context

This part is a member of the MC74ACT574 family, representing a standard octal flip-flop solution. It complements other 74ACT series components like buffers and gates within onsemi's portfolio. The device serves as a fundamental building block for digital logic designs requiring reliable state retention and fast switching speeds in commercial and industrial electronics.

Flip Flops Replacement Considerations

MC74ACT574DWTR2G offers identical electrical characteristics in a SOIC-20 package. MC74AC574DWR2G provides similar functionality but lacks the specific ACT speed optimization. Verify pinout compatibility and package dimensions before substituting to ensure mechanical fit.
