Flip Flops Procurement Notes

Verify the complete part number includes the 'G' suffix indicating RoHS compliance when sourcing. Confirm the TSSOP-20 package dimensions match your PCB footprint requirements precisely. Check moisture sensitivity level classifications for proper handling during assembly processes. Ensure supply voltage specifications align with your system's 5 V logic standards before integration.

Flip Flops Selection Notes

Choose this component when interfacing with TTL-compatible logic levels due to its HCT series characteristics. Consider the 20-TSSOP package for applications requiring compact surface-mount solutions with moderate pin density. Evaluate the 25 ns propagation delay against your system timing constraints to ensure adequate signal integrity. Verify that the operating temperature range meets your specific environmental conditions for long-term reliability.

Flip Flops Part Context

This device belongs to the MC74HCT273A family of octal D-type flip-flops designed for high-speed digital applications. It complements other onsemi logic products by offering robust performance in standard 5 V systems. The HCT series ensures compatibility with previous TTL designs while providing modern CMOS advantages. This specific variant focuses on surface-mount convenience for automated manufacturing processes.

Flip Flops Replacement Considerations

MC74HCT273ADWR2G offers identical electrical specifications but utilizes a SOIC-20 package instead of TSSOP-20. MM74HCT273MTCX provides similar functionality in a TSSOP-20 format from the same manufacturer. Verify pinout compatibility and package dimensions before substituting to ensure proper board layout integration without redesigning footprints.
