100131W-MIL

Overview

The DM54S03J-MIL is a military-grade quad 2-input NAND gate integrated circuit manufactured by National Semiconductor. It utilizes Schottky TTL (S-TTL) technology and is housed in a 14-pin ceramic dual in-line package (DIP). The device operates at a nominal supply voltage of 5 V with a maximum supply current of 36 mA. Key electrical parameters include a propagation delay of 11 ns at nominal supply. It features open-collector outputs and supports an operating temperature range from -55 °C to 125 °C. The component is screened to MIL-STD-883 Class B (Modified) standards.

Feature Summary

• Military-grade reliability screening under MIL-STD-883 Class B (Modified)
• Hermetically sealed ceramic dual in-line packaging for environmental resistance
• Schottky TTL logic architecture ensuring high-speed switching performance
• Open-collector output configuration for flexible interfacing

Applications

• High-reliability aerospace computing systems
• Military communication equipment logic circuits
• Harsh environment industrial control interfaces
• Defense electronics requiring certified component screening

Procurement Notes

Verify that the specific part number corresponds to the DM54S03J-MIL variant, as the provided identifier may be a manufacturer internal code or legacy designation. Confirm compliance with MIL-STD-883 Class B (Modified) screening requirements. Ensure the ceramic DIP package and open-collector output specifications match system design constraints. Validate that the supplier provides traceable documentation for military-grade qualification levels.

Selection Notes

Select this component when military qualification and hermetic sealing are mandatory for the application. The open-collector outputs require external pull-up resistors, which must be accounted for in the circuit design. Verify compatibility with existing Schottky TTL logic families. Consider the thermal management requirements associated with the specified operating temperature range and power dissipation characteristics.

Part Context

This component belongs to the DM54Sxx series of military-grade logic devices produced by National Semiconductor. These parts are designed for applications requiring higher reliability than commercial equivalents. The series includes various logic functions such as NAND, NOR, and flip-flops, all sharing similar packaging and screening standards. The DM54S03 specifically implements the quad 2-input NAND function within this robust product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other manufacturers' military-grade S-TTL quad 2-input NAND gates only if they explicitly meet MIL-STD-883 Class B screening and hermetic ceramic DIP package requirements.
