DM9301J/883

Overview

The DM9301J/883B is a BCD-to-decimal decoder/demultiplexer manufactured by National Semiconductor (Texas Instruments). It utilizes standard TTL logic technology and operates on a nominal supply voltage of 5 V. The device is housed in a 40-pin ceramic DIP package with through-hole terminals, designed for military temperature ranges from -55 °C to 125 °C. It features a propagation delay of 30 ns at nominal supply and draws a maximum supply current of 44 mA. The component meets MIL-STD-883 Class C screening standards.

Feature Summary

• Performs binary-coded decimal to decimal decoding functions using standard TTL technology
• Constructed with a ceramic dual in-line package suitable for high-reliability environments
• Qualified for extended military-grade operating temperatures

Applications

• Military-grade digital decoding systems
• High-reliability industrial control interfaces
• Aerospace telemetry data routing

Procurement Notes

Verify the specific suffix designation, as the provided model lacks the final character found in the source data (DM9301J/883B). Confirm that the procurement specification explicitly requires MIL-STD-883 Class C screening levels. Ensure the order includes the correct ceramic DIP package variant. Validate compliance with RoHS exemptions if applicable, as the component is marked non-compliant. Check for availability of tin/lead terminal finishes.

Selection Notes

Select this component when a BCD-to-decimal conversion function is required within a standard TTL logic family. The choice is driven by the need for military-grade thermal stability and ceramic packaging durability. Consider the 30 ns propagation delay for timing constraints. Evaluate the 44 mA supply current against available power budgets. Verify compatibility with 5 V logic levels in the target circuit design.

Part Context

This part belongs to the DM93 series of high-speed TTL logic devices produced by National Semiconductor. The series is characterized by robust performance in harsh environments. The /883 suffix indicates adherence to MIL-STD-883 microelectronics testing standards. This specific decoder complements other logic gates and flip-flops within the same military qualification tier.
