M74HC74RM13TR

Flip Flops Overview

The M74HC74RM13TR is a dual D-type flip-flop manufactured by STMicroelectronics using silicon gate C2MOS technology. It features two independent positive-edge-triggered D-type flip-flops with clear inputs, housed in a 14-SOIC package (0.154 inch width). The device operates within a supply voltage range of 2V to 6V and supports clock frequencies up to 67MHz. Key electrical parameters include a maximum propagation delay of 13ns at 6V with 50pF load, output drive currents of ±5.2mA, and a static current of 4µA. It functions across an industrial temperature range of -55°C to 125°C.

Flip Flops Feature Summary

• Dual independent D-type flip-flops with positive edge triggering
• High-speed CMOS construction for low power consumption
• Schmitt-trigger action on all inputs for noise immunity

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• Timing control logic systems

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors due to the prevalence of counterfeits in the logic IC market. Confirm that the 14-SOIC package dimensions match your PCB footprint requirements. Ensure the operating voltage range aligns with your system's power supply rails. Check for RoHS compliance documentation if required by your manufacturing standards. Validate lead times as availability may fluctuate based on production cycles.

Flip Flops Selection Notes

Select this component when dual independent storage elements are required in a compact surface-mount package. Consider the 67MHz speed limit for high-frequency applications. Evaluate the ±5.2mA output drive capability against load requirements. Compare performance metrics with alternative manufacturers if specific timing constraints exist. Verify compatibility with existing logic families in the design.

Flip Flops Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It is functionally compatible with other 74HC74 variants from different manufacturers. The RM13 suffix indicates tape and reel packaging for automated assembly. It serves as a fundamental building block for sequential logic designs requiring dual bit storage capabilities.

Flip Flops Replacement Considerations

Direct substitutes include the 74HC74D,653 from Nexperia and equivalent parts from Texas Instruments. Verify pinout compatibility before substitution. Ensure electrical specifications such as propagation delay and output current meet design requirements. Check package dimensions to confirm mechanical fit.
