100302PC

Overview

The Fairchild Semiconductor 100302PC is a low-power quint 2-input OR/NOR gate belonging to the 100K series. It features configurable outputs and operates in ECL logic family standards. The device is housed in a 24-pin Plastic Dual In-Line Package (PDIP) with a 0.400-inch width, conforming to MS-010 specifications. It supports through-hole mounting and includes Schmitt trigger inputs for noise immunity. The component functions as a differential output logic gate, providing versatile signal processing capabilities within digital circuits.

Feature Summary

• Configurable differential outputs for flexible logic implementation
• Schmitt trigger inputs enhance noise immunity
• Low-power consumption characteristics suitable for energy-efficient designs

Applications

• Digital signal processing systems requiring NOR/OR logic functions
• High-speed data transmission interfaces utilizing ECL standards
• Industrial control units needing noise-resistant input stages

Procurement Notes

Verify the manufacturer designation carefully, as Fairchild's semiconductor division was acquired by ON Semiconductor. Confirm the specific package variant matches the 24-DIP requirement. Ensure the order suffix aligns with the desired packaging type, typically bulk for this component. Check RoHS compliance status as indicated in official documentation, noting potential non-compliance markers in some databases. Validate the active product status with authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when designing circuits that require multiple independent 2-input OR or NOR gates within a single package. The ECL compatibility makes it suitable for high-speed applications where propagation delay is critical. Consider the PDIP package constraints for PCB layout and thermal management. Verify that the supply voltage levels match the specific ECL standard required by the system architecture to ensure proper logic level translation and performance.

Part Context

The 100302PC is part of Fairchild's 100K series of high-speed ECL logic devices. This series was widely used in telecommunications and computing equipment during the era of emitter-coupled logic dominance. The quint configuration allows for significant circuit density reduction compared to using individual gates. As a legacy component, it remains relevant in maintenance and retrofit projects for established industrial and communication infrastructure.

Replacement Considerations

Direct pin-compatible substitutes may include other 100K series ECL gates from Fairchild or compatible manufacturers. Verify logical equivalence and electrical parameters such as propagation delay and power dissipation. Cross-reference with ON Semiconductor equivalents if sourcing from current inventory. Ensure any replacement maintains the same DIP-24 package dimensions and pinout configuration.
