100142FC

Overview

The 100142FC is a Content Addressable Memory (CAM) integrated circuit manufactured by National Semiconductor. It features a 16-bit parallel interface architecture with a specified access time of 4.5 ns. The device is housed in a 24-pin CFlatPack package, providing a compact form factor for memory applications requiring rapid data retrieval capabilities.

Feature Summary

• Supports Content Addressable Memory operations for high-speed parallel data matching
• Utilizes a 16-bit wide parallel interface for data input and output
• Delivers fast 4.5 ns access times suitable for performance-critical systems

Applications

• High-speed network switching and routing hardware
• Packet classification and filtering engines
• Hardware-based lookup table implementations

Procurement Notes

Verify the manufacturer origin as National Semiconductor, noting that the company has undergone corporate restructuring. Confirm the specific package type is the 24-CFlatPack variant. Ensure the datasheet specifies the 4.5 ns timing parameters to match system requirements. Check for any obsolescence notices or recommended alternative part numbers from current manufacturers holding the legacy portfolio rights.

Selection Notes

Select this component when CAM functionality is required rather than standard SRAM or DRAM. The 16-bit width dictates the bus interface compatibility. The 4.5 ns speed rating must align with the system clock frequency. The CFlatPack package requires appropriate PCB footprint design considerations for thermal dissipation and pin alignment during assembly.

Part Context

This component belongs to the National Semiconductor memory product line, specifically within the CAM category. It represents legacy semiconductor technology designed for specialized parallel processing tasks. The part number identifies a specific configuration within the broader family of content-addressable memory devices produced by the manufacturer.

Replacement Considerations

Consult official manufacturer documentation for direct cross-reference part numbers. Verify electrical compatibility including voltage levels and interface protocols before substitution.
