Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging if required for automated assembly. Confirm the 'LF' designation ensures lead-free compliance per current environmental standards. Ensure the order specifies the wide-body variant to match footprint constraints. Validate that the military temperature rating aligns with your system's operational envelope. Request batch traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a dual 4-input NAND function with tri-state capability is necessary. The Schottky speed profile suits high-frequency digital circuits. Consider the wide-body package for superior heat management compared to standard variants. Verify voltage compatibility with existing 5V logic families. Evaluate pin-out compatibility against legacy designs requiring direct replacement.

Part Context

Rochester Electronics specializes in continuing supply solutions for obsolete and end-of-life semiconductors. This part belongs to the SN54 series, originally defined by Texas Instruments. The company ensures performance matches original OEM specifications through rigorous testing. Components are often sourced from authorized continuing sources or recreated wafers. This approach supports long-term maintenance for critical infrastructure systems.

Replacement Considerations

Direct substitutes include the SN5482WJ or SN5482W. Verify pin compatibility before substitution. Ensure the alternative maintains the same Schottky logic family characteristics. Check if the replacement offers identical three-state output functionality. Confirm military temperature ratings match the original design requirements.
