Flip Flops Procurement Notes

Verify the exact part number suffix when ordering, as variants such as MC74VHC374DTR2G exist with different packaging options like TSSOP-20 or reel/cut tape formats. Confirm that the specific 'DWR2' designation matches the required SOIC-20 package and manufacturer specifications. Cross-reference official datasheets to ensure compatibility with system voltage and temperature requirements before procurement.

Flip Flops Selection Notes

Select this component when an octal D-type flip-flop with three-state outputs is required for bus-driven architectures. The 74VHC series offers a balance of speed and voltage flexibility compared to standard HC or LVX families. Ensure the design accommodates the specified propagation delay and output drive capabilities. Consider thermal management if operating near the maximum temperature limits defined in the datasheet.

Flip Flops Part Context

This component is part of onsemi's extensive portfolio of 74VHC logic integrated circuits. The 74VHC series is designed for high-speed CMOS applications with performance comparable to TTL but at lower voltages. The octal flip-flop topology is a standard building block in digital electronics, widely used for temporary data storage and synchronization in microprocessor-based systems.

Flip Flops Replacement Considerations

Direct substitutes may include other manufacturers' octal D-type flip-flops with three-state outputs in SOIC-20 packages, such as those from Texas Instruments or NXP. Verify pinout compatibility and electrical characteristics like propagation delay and output current before substitution. Alternative onsemi parts like MC74VHC374ADTR2G offer similar functionality but in different packages.
