Flip Flops Procurement Notes

Verify the specific suffix 'N' against official onsemi documentation to confirm the exact package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing process. Cross-reference the datasheet revision date to confirm electrical characteristics match your design constraints. Confirm availability status as product lifecycles may change.

Flip Flops Selection Notes

Select this component when designing systems requiring octal data latching with high-speed operation. The ACT series offers a balance of speed and power consumption suitable for 5V CMOS applications. Consider the 24mA output drive strength for driving multiple loads or longer traces. Ensure the 20-SOIC package footprint aligns with your PCB layout constraints and thermal management requirements.

Flip Flops Part Context

This part belongs to the 74ACT family of high-speed CMOS logic devices produced by onsemi. The 74ACT series is designed to be pin-compatible with standard 74LS logic while offering significantly faster switching speeds and lower power dissipation. The MC74ACT273 specifically addresses the need for octal register functions in modern digital systems requiring reliable data retention and fast clocking capabilities.

Flip Flops Replacement Considerations

MC74AC273N: Similar function but lacks TTL-compatible inputs; verify voltage compatibility. MC74HC273N: Higher voltage range (2V-6V) but slower speed; check timing constraints. CD74ACT273M96: Texas Instruments equivalent; verify package and pinout compatibility.
