DM9301W/883

Overview

The DM9301W/883 is a BCD-to-decimal decoder/driver manufactured by National Semiconductor. It operates on a 5 V supply and features a ceramic flatpack (DFP) package with 14 pins. The device functions as a binary counter in asynchronous mode, supporting an up-counting direction. It has a maximum operating frequency of 6 MHz and a maximum power supply current of 5.5 mA. The component is rated for operation between -55 °C and +125 °C.

Feature Summary

• BCD-to-decimal decoding functionality
• Asynchronous counting operation
• Ceramic flatpack construction

Applications

• Digital counting circuits
• Decoding logic systems
• Industrial control interfaces

Procurement Notes

Verify the specific datasheet for the DM9301W/883 variant to confirm pinout compatibility and electrical characteristics against system requirements. Ensure the ceramic flatpack package dimensions match the PCB footprint. Confirm that the 5 V supply voltage aligns with the target application's power rails. Check for any specific handling instructions related to the ceramic packaging material.

Selection Notes

Select this component when a robust, high-temperature capable BCD-to-decimal decoder is required. The ceramic flatpack package offers durability suitable for harsh environments. Verify that the 6 MHz maximum frequency meets the system's timing constraints. Consider the 5.5 mA power consumption if energy efficiency is a critical design parameter.

Part Context

This part belongs to the National Semiconductor DM93xx series of logic integrated circuits. These components are designed for standard TTL applications and are often used in military or aerospace contexts due to their wide temperature range and ceramic packaging. The /883 suffix typically indicates compliance with MIL-STD-883 standards.

Replacement Considerations

Check for direct equivalents from Texas Instruments, which acquired National Semiconductor. Verify pin-for-pin compatibility with other DM9301 variants or similar BCD decoders from manufacturers like ON Semiconductor or Microchip Technology.
