Flip Flops Procurement Notes

Verify the specific package designation matches the required PCB footprint, as the NS suffix indicates a plastic dual in-line package (PDIP). Confirm that the manufacturing source aligns with authorized distribution channels to ensure component authenticity. Check datasheet revisions for any updates regarding mechanical dimensions or electrical characteristics before finalizing procurement specifications.

Flip Flops Selection Notes

Select this component when an octal flip-flop with three-state outputs is required for parallel data handling. The ACT series offers a balance of speed and power consumption suitable for general-purpose logic applications. Ensure the design accommodates the 20-pin PDIP form factor and through-hole assembly process. Verify that the system voltage remains within the specified 4.5 V to 5.5 V operational range.

Flip Flops Part Context

This part is a member of the SN74ACT family, which provides advanced CMOS performance with TTL compatibility. It serves as a standard solution for storing eight bits of data in synchronous digital designs. The device complements other logic components by providing reliable clocked data retention and high-drive output capabilities for interfacing with external circuitry.

Flip Flops Replacement Considerations

SN74ACT574N is a direct equivalent offering identical functionality in a PDIP-20 package. SN74ACT574DWR provides the same logical operations but utilizes a surface-mount SOIC-20 package instead of through-hole mounting.
