MC74HC74AFR2

Flip Flops Overview

The MC74HC74AFR2 is a dual D-type flip-flop manufactured by onsemi, featuring independent Set and Reset inputs. It operates within a supply voltage range of 2.0 V to 6.0 V and utilizes high-performance silicon-gate CMOS technology. The device provides non-inverting Q and complementary Q outputs for each flip-flop, with information transferred on the positive clock edge. It is housed in an SOIC-14 surface-mount package and supports industrial temperature ranges.

Flip Flops Feature Summary

• High noise immunity characteristic of CMOS devices
• Outputs directly interface to CMOS, NMOS, and TTL loads

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose digital storage elements

Flip Flops Procurement Notes

Verify the specific suffix 'FR2' against official datasheets to confirm tape-and-reel packaging details and moisture sensitivity levels. Ensure the ordering part number matches the exact pinout and electrical specifications required for your design. Cross-reference with manufacturer documentation to validate RoHS compliance status and lead times.

Flip Flops Selection Notes

Select this component when a dual D-flip-flop with dedicated Set/Reset functionality is required in a compact SOIC-14 package. It is suitable for designs needing compatibility with standard CMOS outputs and operation across a wide voltage range from 2.0 V to 6.0 V. Consider its propagation delay and drive capability relative to system timing requirements.

Flip Flops Part Context

This part belongs to the MC74HC74A series of dual D-type flip-flops. It shares pinout compatibility with legacy LS74 devices while offering improved performance through modern CMOS technology. The series is designed for applications requiring reliable data storage and synchronization in digital logic systems.

Flip Flops Replacement Considerations

Direct substitutes include MC74HC74ADG and MC74HC74D. Verify package dimensions and pin configurations before substitution. Ensure electrical parameters such as operating voltage and output drive current meet application requirements.
