MC74ACT273DWR2G

Flip Flops Overview

The MC74ACT273DWR2G is an octal D-type flip-flop from onsemi's 74ACT logic series, designed for high-speed digital applications. It features eight non-inverting D-type flip-flops with edge-triggered operation and a master reset function. The device operates within a supply voltage range of 4.5 V to 5.5 V, ensuring compatibility with standard 5V CMOS systems. Key electrical parameters include a propagation delay of 11 ns, output drive currents of ±24 mA, and a maximum clock frequency supporting rapid data transitions. It is housed in a 20-SOIC surface-mount package and supports industrial temperature ranges from -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration integrating eight independent D-type flip-flops into a single integrated circuit for parallel data storage.
• Edge-triggered architecture ensures data capture occurs precisely at the active clock transition, maintaining timing integrity.
• Master reset functionality allows simultaneous clearing of all flip-flop outputs to a defined low state via a dedicated control input.
• High-drive capability provides symmetrical output current sourcing and sinking to support direct interfacing with heavy loads.

Flip Flops Applications

• Parallel data storage registers in microprocessor-based systems
• Shift register configurations for serial-to-parallel data conversion
• Timing synchronization circuits for clock domain crossing
• State machine implementation in digital control logic

Flip Flops Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches SOIC-20 requirements for PCB footprint compatibility. Ensure supply chain sources provide valid RoHS compliance documentation. Validate moisture sensitivity level handling procedures during storage and reflow soldering processes to prevent internal damage.

Flip Flops Selection Notes

Select this component when designing 5V logic systems requiring high-speed data latching with strong drive capabilities. The ACT series offers TTL-compatible input thresholds while maintaining CMOS noise immunity. Consider the 11 ns propagation delay for timing budget analysis in high-frequency designs. Evaluate the 20-SOIC package constraints regarding board space and thermal dissipation needs compared to alternative packages.
