MC74ACT273MG

Flip Flops Overview

The MC74ACT273MG is an octal D-type flip-flop manufactured by onsemi, belonging to the 74ACT logic series. It features a positive-edge clock trigger and non-inverting outputs within a single element configuration. The device operates on a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 200 MHz. Key electrical parameters include a propagation delay of 11 ns at 5 V with 50 pF load, output drive currents of ±24 mA, and static current of 8 µA. It is housed in a 20-SOIC package (SOEIAJ-20) and functions within a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with positive-edge triggering for synchronized data capture.
• High-speed performance capability supporting up to 200 MHz clock frequencies.
• Robust output drive strength providing ±24 mA current capacity for reliable signal transmission.

• State machine implementation in control logic
• Buffering applications for data latching

Flip Flops Procurement Notes

Verify component authenticity through authorized distribution channels due to potential availability of counterfeit devices. Confirm RoHS compliance status via official datasheets as environmental regulations vary by region. Check for specific ordering suffixes that may indicate packaging variations or lead-free processing requirements. Ensure compatibility with existing PCB footprints, specifically the 20-SOEIAJ package dimensions, before finalizing procurement decisions.

Flip Flops Selection Notes

Select this component when high-speed octal latching is required within standard 5V CMOS logic environments. Compare against HCT series alternatives if lower power consumption is prioritized over speed, noting the significant difference in propagation delay. Evaluate package constraints to ensure the SOEIAJ-20 footprint fits the design layout. Consider the ±24 mA output drive capability when determining load requirements for downstream logic gates.

Flip Flops Part Context

This part belongs to the 74ACT family of advanced CMOS logic devices, offering performance comparable to TTL but with lower power consumption. The 74ACT273 variant specifically provides eight independent D-type flip-flops with common clock and master reset lines. It serves as a fundamental building block for sequential logic circuits requiring parallel data storage and synchronous operation in industrial and consumer electronics.
