MC74HC74AFELG

Flip Flops Overview

The MC74HC74AFELG is a dual D-type flip-flop manufactured by onsemi, belonging to the 74HC logic family. It features independent Set and Reset inputs for each flip-flop, with data transfer occurring on the positive clock edge. The device operates within a supply voltage range of 2.0 V to 6.0 V. Key electrical parameters include a maximum static current of 2 µA and output drive capabilities supporting 10 LSTTL loads. Propagation delay varies from 17 ns at 6 V to higher values at lower voltages. It is housed in a 14-SOIC package and supports surface-mount installation.

Flip Flops Feature Summary

• Dual D-type flip-flops with asynchronous Set and Reset controls
• High-noise immunity and low power consumption typical of CMOS technology
• Outputs directly interface with CMOS, NMOS, and TTL logic families

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• Timing and synchronization logic in digital systems

Flip Flops Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as historical batches may vary. Check for moisture sensitivity level (MSL) handling requirements prior to assembly. Ensure the specific suffix matches design specifications for package and temperature grade variations.

Flip Flops Selection Notes

Select this component when dual independent storage elements are required in a compact SOIC footprint. Consider the 2V to 6V operating range for compatibility with various logic levels. Evaluate propagation delay specifications against system timing constraints. Verify that the input capacitance and drive strength meet the source and load requirements of the application circuit.

Flip Flops Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices produced by onsemi. The 74HC family is designed to be pinout compatible with older 74LS logic standards while offering improved speed and lower power consumption. The MC74HC74AFELG specifically denotes the dual D-flip-flop variant with an A-grade temperature rating and ELG packaging suffix.

Flip Flops Replacement Considerations

Publicly confirmed substitute part numbers include SN74HC74NSR from Texas Instruments and 74HC74PW from Nexperia. These alternatives offer functional and pinout compatibility. Verify voltage ranges and package dimensions before substitution.
