100102J-MIL

Overview

The 100102J-MIL is a multi-function logic gate integrated circuit manufactured by National Semiconductor. It features five configurable circuits capable of operating as OR or NOR gates. The device accommodates ten inputs distributed across the five circuits, with two inputs per circuit. It is housed in a 24-lead Ceramic Dual In-Line Package (CDIP). This component belongs to the 100K series logic family, designed for digital logic applications requiring flexible gate configuration within a military-grade package format.

Feature Summary

• Configurable logic architecture allowing selection between OR and NOR gate functions
• Five independent logic circuits providing versatile signal processing capabilities
• Ten-input capacity distributed across multiple channels for complex logic operations
• Ceramic dual in-line packaging suitable for high-reliability environments

Applications

• Digital logic systems requiring reconfigurable gate structures
• Military and aerospace electronic assemblies demanding ceramic packaging
• Signal routing and inversion circuits in industrial control systems
• Legacy system maintenance where 100K series compatibility is required

Procurement Notes

Verify that the specific part number matches the exact configuration requirements, as logic families may have subtle electrical differences. Confirm the package type is indeed 24-CDIP, as suffixes can indicate plastic variants or different pinouts. Ensure the source provides traceability documentation if the application requires military or high-reliability standards. Check for obsolescence status given the manufacturer's acquisition history.

Selection Notes

Select this component when a fixed logic function is insufficient and hardware reconfiguration is not feasible. The 100K series offers established performance characteristics for standard digital interfaces. Consider the physical size constraints of the 24-CDIP package during board layout. Evaluate whether the configurable nature of the five circuits reduces the total component count compared to using discrete gates.

Part Context

National Semiconductor was acquired by Texas Instruments, which now manages the legacy product portfolio. The 100102J-MIL represents a historical logic component from the 100K series. These devices were widely used before the dominance of modern FPGAs and CPLDs. The 'MIL' suffix typically denotes military qualification or ceramic packaging standards distinct from commercial plastic versions.

Replacement Considerations

Direct replacements may include other 100K series NOR/OR gates in 24-CDIP packages from National Semiconductor or Texas Instruments. Verify pin-to-pin compatibility and logical truth tables before substitution. Generic logic gates do not offer the same configurability, potentially requiring multiple components.
