Procurement Notes

Verify the specific suffix F3A against official datasheets to confirm military-grade specifications and packaging details. Confirm availability status as distribution channels may indicate limited stock or special order requirements. Ensure the procurement source provides valid traceability documentation for this specific part number variant.

Selection Notes

Select this component when an octal D-type flip-flop with industrial temperature range is required. The HCT series ensures compatibility with standard TTL logic levels while offering CMOS power efficiency. Verify that the 16-CDIP through-hole package aligns with the target PCB design constraints and mechanical mounting requirements.

Part Context

This part belongs to the CD54HCT273 family of octal D-type flip-flops. It shares functional similarities with other HCT series devices but is distinguished by its specific military-grade temperature rating and ceramic dual in-line package. The family focuses on high-speed digital storage applications requiring robust performance under varying environmental conditions.

Replacement Considerations

Check for direct pin-compatible alternatives within the same HCT family. Verify if lower-cost commercial variants meet the required temperature specifications. Ensure any substitute maintains the same octal configuration and TTL input compatibility.
