Procurement Notes
Verify the manufacturer designation as Rochester Electronics, LLC, which supplies components often sourced from original equipment manufacturer wafers or recreated dies. Confirm the specific package type is DIP-14 and ensure the operating temperature range meets the required -55°C to +125°C specification for your application environment before finalizing procurement.
Selection Notes
Select this component when a robust 4-bit binary counter is required for high-reliability environments. The wide operating temperature range makes it suitable for aerospace or defense applications where standard commercial parts would fail. Ensure the circuit design accommodates the specified propagation delay characteristics for timing-sensitive operations.
Part Context
This part belongs to the SN54xx series of logic integrated circuits, specifically designed for military specifications. Rochester Electronics specializes in providing lifecycle support for obsolete or hard-to-find semiconductor devices, ensuring continuity for critical systems that rely on legacy logic families like TTL.
Replacement Considerations
Direct substitutes include other SN5493 variants such as SN5493J or SN5493FK, provided they match the DIP-14 package and temperature ratings. Verify pin compatibility and electrical characteristics against the original system requirements before substitution.
