MM74C74M

Flip Flops Overview

The MM74C74M is a dual D-type flip-flop from onsemi's 74C series, housed in a 14-SOIC package. It operates within a supply voltage range of 3 V to 15 V and features positive-edge triggering with preset and reset functions. The device exhibits a maximum propagation delay of 300 ns at 10 V with 50 pF load, while static current consumption is specified at 60 µA. Output drive capability reaches 8 mA for both high and low states. It supports an extended industrial temperature range from -55°C to +125°C.

Flip Flops Feature Summary

• Dual D-type flip-flop architecture with positive-edge clock triggering
• Integrated asynchronous preset and reset control inputs
• Complementary MOS construction for low static power consumption
• Extended industrial temperature rating for harsh environments

Flip Flops Applications

• Data storage and register circuits
• Shift register configurations
• Timing and synchronization logic
• State machine implementations

Flip Flops Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Check for obsolescence notices and confirm availability via secondary market suppliers like Rochester Electronics. Ensure replacement parts meet identical electrical specifications and pin compatibility for seamless integration into existing designs without modification.

Flip Flops Selection Notes

Select this component for applications requiring wide voltage operation up to 15 V and broad temperature resilience. Consider the 74C series characteristics for lower speed but higher noise immunity compared to HC variants. Evaluate alternative sources if original manufacturing supply is unavailable, ensuring functional equivalence in timing and drive capabilities.

Flip Flops Part Context

This part belongs to onsemi's legacy 74C CMOS logic family, designed for robust performance in industrial settings. The MM74C74M specifically provides dual independent D-type flip-flops in a standard surface-mount package. It represents a transition-era component bridging older TTL-compatible logic levels with modern CMOS efficiency, now largely superseded by newer series.
