MM74HCT74MX

Flip Flops Overview

The MM74HCT74MX is a dual D-type flip-flop manufactured by Fairchild Semiconductor in the 74HCT logic series. It features positive-edge triggering and is housed in a 14-SOIC package with a width of 0.154 inches (3.90mm). The device operates on a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to 85°C. It provides separate data inputs, clock inputs, and clear inputs for each flip-flop element.

Flip Flops Feature Summary

• Dual D-type flip-flop configuration with positive-edge clock triggering
• Separate data, clock, and clear inputs for independent operation
• TTL-compatible input levels ensuring compatibility with standard logic families

Flip Flops Applications

• Digital data storage and register circuits
• Shift register implementations
• Timing and synchronization control systems

Flip Flops Procurement Notes

Verify the manufacturer part number MM74HCT74MX against official Fairchild or ON Semiconductor documentation to confirm pinout and electrical specifications. Ensure the 14-SOIC package dimensions match design constraints. Check for RoHS compliance status if required by project regulations. Confirm active status through authorized distributors.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop with HCT logic compatibility is required. It is suitable for designs needing positive-edge triggered storage elements within the 4.5V to 5.5V supply range. Consider the 14-SOIC surface-mount package for PCB layout integration. Verify that the propagation delay characteristics meet the system timing requirements.

Flip Flops Part Context

This component belongs to the 74HCT series of high-speed CMOS logic devices. The series is designed to interface directly with TTL logic inputs while offering CMOS noise immunity and power efficiency. The MM74HCT74MX specifically implements two independent D-type flip-flops, providing a compact solution for sequential logic applications compared to discrete transistor designs.

Flip Flops Replacement Considerations

Compatible substitutes include other manufacturers' equivalents such as SN74HCT74N or MC74HCT74ADTR2G, provided they share the same 14-SOIC package and logical functionality. Always verify pin-to-pin compatibility and electrical parameters before substitution.
