MC74ACT74DTR2

Flip Flops Overview

The MC74ACT74DTR2G is a dual D-type positive-edge triggered flip-flop from the 74ACT logic series, manufactured by onsemi. It operates within a supply voltage range of 4.5V to 5.5V and features a propagation delay of 11ns at 5V with 50pF load. The device provides complementary outputs with high drive capability of ±24mA and low static current of 4µA. Packaged in a 14-SOIC surface-mount format, it supports preset and reset functions and operates reliably across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Complementary output configuration providing both non-inverting and inverting signals
• High noise immunity and robust drive strength suitable for demanding digital applications

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations in communication systems
• General-purpose storage elements in microprocessor interfaces

Flip Flops Procurement Notes

Verify the complete part number includes the trailing 'G' suffix (MC74ACT74DTR2G) as this indicates RoHS compliance and specific manufacturing lot codes. Confirm package type matches design requirements, as variants exist in SOIC and TSSOP formats. Cross-reference official datasheets for exact pinout and electrical characteristics before finalizing procurement specifications.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop with ACT logic speed and 5V operation is required. Ensure the design accommodates the 14-pin SOIC footprint and thermal constraints. Compare against MC74AC74DTR2G if lower voltage operation or different packaging is needed, noting that AC and ACT series differ in speed and voltage tolerance profiles.

Flip Flops Part Context

This component belongs to the 74ACT family, which bridges the performance gap between standard CMOS and TTL logic. It offers faster switching speeds than AC series while maintaining CMOS power efficiency. The part is widely used in industrial and consumer electronics requiring reliable synchronous data handling at standard 5V logic levels.

Flip Flops Replacement Considerations

MC74ACT74DG is a direct replacement in 14-SOIC package. MC74AC74DTR2G serves as an alternative in TSSOP-14 with similar functionality but different electrical characteristics.
