5433J/B

Overview

The 5433J/B is a quad 2-input positive-NOR buffer manufactured by Rochester Electronics, LLC. It features open-collector outputs designed for bus-oriented systems and wired-OR applications. The device provides full binary decoding data selection capabilities through inverters and drivers connected to AND-OR-invert gates. Separate strobe inputs control each section, allowing individual output enablement. The three-state outputs interface with data lines, driving bus lines to high or low logic levels when enabled.

Feature Summary

• Quad configuration with two-input positive-NOR buffering architecture
• Open-collector output structure supporting wired-OR logic functions
• Individual strobe inputs for independent section control
• Three-state outputs compatible with bus-organized system architectures

Applications

• Bus-oriented digital systems requiring signal buffering
• Wired-OR logic implementation in memory addressing
• Data selector interfaces in military aerospace environments
• Signal routing in complex logic gate networks

Procurement Notes

Verify component authenticity against original manufacturer specifications. Confirm package type matches requirements. Check date codes for lifecycle status. Ensure compliance with relevant quality certifications such as MIL-PRF-38535 if applicable. Validate testing procedures meet original factory standards.

Selection Notes

Select this component for applications requiring quad NOR buffering with open-collector outputs. Consider the device's compatibility with bus systems and its ability to handle wired-OR configurations. Evaluate the need for separate strobe controls per section. Verify voltage levels and current drive capabilities match system design constraints.

Part Context

Rochester Electronics specializes in manufacturing and distributing legacy and obsolete semiconductor components. The 5433J/B falls under their portfolio of logic integrated circuits, specifically buffers and inverters. These components are often sourced from original manufacturers or recreated using approved intellectual property to maintain supply chain continuity for critical applications.

Replacement Considerations

Check for direct pin-compatible substitutes within the same logic family. Verify electrical characteristics match original specifications. Confirm package dimensions and mounting requirements align with existing board layouts. Review availability of alternative vendors offering equivalent performance.
