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 features open-collector outputs. The device is housed in a 14-pin ceramic dual in-line package (DIP). It operates within a supply voltage range of 5 V, with a maximum power supply current of 36 mA. The propagation delay at nominal supply is 11 ns. The component is qualified to MIL-STD-883 Class B (Modified) standards and functions reliably across an extended temperature range from -55 °C to 125 °C.
Verify that the specific part number corresponds to the DM54S03J-MIL variant, as National Semiconductor was acquired by Texas Instruments. Confirm that the ordering suffix indicates the correct MIL-STD-883 Class B (Modified) screening level. Ensure the ceramic DIP package matches the required form factor for the target application. Check for any specific lot traceability requirements mandated by the procurement contract. Validate that the open-collector output type aligns with the system design constraints.
Select this component when high-speed Schottky TTL performance is required alongside strict military reliability standards. The open-collector outputs necessitate external pull-up resistors, which must be accounted for in the circuit design. Consider the thermal management capabilities provided by the ceramic package if operating near the upper temperature limit. Compare against other S-TTL devices to ensure compatibility with existing logic families in the system architecture.
This component belongs to the DM54Sxx series of Schottky TTL logic gates produced by National Semiconductor. The 'J' suffix typically denotes a ceramic dual in-line package, while 'MIL' indicates military qualification. This series is part of the broader standard transistor-transistor logic portfolio, offering faster switching speeds than standard TTL variants. The DM54S03 specifically implements the NAND function, a fundamental building block in digital logic design.
Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official Texas Instruments or National Semiconductor cross-reference guides for equivalent military-grade Schottky NAND gates. Verify pinout compatibility and electrical characteristics before substituting with similar components.
