DM54S241J-MIL

Overview

The DM54S241J-MIL is a military-grade, 4-bit bus driver manufactured by National Semiconductor. It features two independent buffers with three-state outputs and non-inverting logic. The device utilizes Schottky TTL technology and is housed in a 20-pin ceramic dual in-line package (CDIP). It operates within a temperature range of -55°C to 125°C and requires a nominal 5V supply voltage.

Feature Summary

• Military-grade reliability certified under MIL-STD-883 Class B standards
• Three-state output capability for effective bus line isolation
• Non-inverting buffer architecture supporting high-speed digital signaling

Applications

• Military aerospace electronic systems requiring high-reliability logic components
• High-speed data bus interfaces in harsh environmental conditions
• Buffering applications in specialized communication equipment

Procurement Notes

Verify the specific MIL-STD-883 Class B screening level documentation upon receipt. Confirm the ceramic package integrity and pin configuration match the CDIP20 specification. Ensure the component lot aligns with current availability from authorized distributors or surplus suppliers, as this is a specialized military part.

Selection Notes

Select this component when military qualification and wide temperature operation are mandatory. Compare against standard commercial variants if environmental constraints allow. Verify that the three-state control logic matches the system design requirements for bus arbitration.

Part Context

This part belongs to the DM54 series of Schottky TTL logic devices produced by National Semiconductor. The 'MIL' suffix indicates it meets strict military quality standards. It serves as a robust alternative to commercial logic families in defense and space applications where failure is not an option.

Replacement Considerations

The SN74S241J is a commercial equivalent but lacks military screening. Direct substitution requires verifying that the application does not mandate MIL-STD-883 compliance or the extended -55°C to 125°C temperature range.
