MM74HC174N

Flip Flops Overview

The MM74HC174N is a hex D-type flip-flop manufactured by Fairchild Semiconductor, belonging to the 74HC logic series. It features six independent positive-edge-triggered flip-flops with direct clear inputs in a 16-pin PDIP package. The device operates on a supply voltage range of 2V to 6V and supports an operating temperature from -40°C to +85°C. Key electrical parameters include a propagation delay of 165ns at 5V with 50pF load, output currents of ±5.2mA, and maximum quiescent current of 2µA.

Flip Flops Feature Summary

• Hex configuration providing six independent D-type flip-flops within a single integrated circuit
• Positive-edge triggering mechanism synchronized with clock signal transitions
• Direct clear input functionality for immediate asynchronous reset of all flip-flops
• CMOS construction ensuring low power consumption while maintaining TTL-compatible input levels

Flip Flops Applications

• Parallel data storage registers in digital systems
• Shift register configurations for serial-to-parallel conversion
• Pattern generation circuits requiring sequential state management
• Buffer memory elements in microprocessor interfacing applications

Flip Flops Procurement Notes

Verify manufacturer part number accuracy against official Fairchild or onsemi documentation. Confirm package type matches specific design requirements. Check component status for availability as distribution channels may vary. Ensure environmental compliance certifications align with project specifications. Validate electrical characteristics against target application constraints before integration.

Flip Flops Selection Notes

Select this component when hex D-flip-flop functionality is required with standard HC logic speed. Consider the 16-pin DIP package for through-hole mounting applications. Evaluate propagation delay specifications against system timing requirements. Compare power consumption metrics with alternative logic families if energy efficiency is critical. Verify voltage compatibility with existing system supply rails.

Flip Flops Part Context

The MM74HC174N belongs to the widely adopted 74HC family of high-speed CMOS logic devices. This series bridges performance gaps between older TTL technologies and modern ultra-high-speed variants. The hex flip-flop configuration provides compact solution for multi-bit storage needs. Fairchild Semiconductor, now part of onsemi, maintains extensive documentation for this legacy component line.

Flip Flops Replacement Considerations

Equivalent parts include SN74HC174 from Texas Instruments and CD74HC174 from Harris Semiconductor. These alternatives maintain pin compatibility and logical function while potentially differing in electrical specifications. Verify package dimensions and thermal characteristics when substituting manufacturers. Cross-reference datasheets for minor parameter variations affecting system performance.
