Procurement Notes
This component is identified as a military-grade part with restricted availability. Verification of current stock status and lead times is required directly with authorized distributors or the manufacturer. Ensure that procurement channels are qualified for handling military-specification integrated circuits to maintain integrity and traceability throughout the supply chain.
Selection Notes
Select this part when an octal D-type flip-flop with military qualification is required. The SN54AHC273 series offers high-speed CMOS performance with wide voltage tolerance. Consider the 16-CDIP package for through-hole applications requiring robust mechanical stability. Verify that the direct clear functionality aligns with system reset requirements before integration into the design.
Part Context
The 5962-9853001QRA belongs to the SN54AHC273 family of octal D-type flip-flops manufactured by Texas Instruments. This specific part number denotes a QML (Qualified Military List) version, ensuring compliance with stringent military standards. It serves as a digital memory element within larger logic systems, providing stable data retention and transfer capabilities under extreme operational conditions.
Replacement Considerations
Compatible substitutes include other SN54AHC273 variants with matching military qualifications. Verify pin compatibility and electrical specifications against the original datasheet. Ensure that any replacement maintains the same CDIP package style and temperature rating for direct board-level interchangeability without redesign.
