DM93S41N

Specialty Logic Overview

The DM93S41N is a standard 4-bit Arithmetic Logic Unit (ALU) manufactured by Fairchild Semiconductor. It utilizes Schottky TTL technology and operates in asynchronous mode. The device features open-collector outputs and is housed in a 16-pin ceramic dual in-line package (CDIP). It supports a wide operating temperature range from -55°C to 125°C, suitable for military applications.

Specialty Logic Feature Summary

• Executes arithmetic and logic operations on 4-bit data words
• Utilizes Schottky TTL technology for high-speed performance
• Features open-collector output configuration

Specialty Logic Applications

• Military-grade computing systems
• High-speed digital signal processing
• Industrial control units requiring wide temperature tolerance

Specialty Logic Procurement Notes

Verify the specific suffix 'N' corresponds to the ceramic DIP package and leaded terminals as documented. Confirm that the component meets the required MIL-STD screening levels if intended for defense or aerospace use. Ensure compatibility with existing TTL logic families regarding voltage levels and open-collector termination requirements.

Specialty Logic Selection Notes

Select this component when a dedicated 4-bit ALU with Schottky speed is required within a military temperature environment. The open-collector outputs necessitate external pull-up resistors for proper logic high states. Consider the physical dimensions of the CDIP16 package during PCB layout planning.

Specialty Logic Part Context

This part belongs to the Fairchild 93S series of Schottky TTL logic devices. It serves as a functional equivalent to other industry-standard 4-bit ALUs such as the SN54LS181 or DM54LS181, providing arithmetic and logical computation capabilities for complex digital circuits.

Specialty Logic Replacement Considerations

Compatible substitutes include the SN54LS181 and DM54LS181. Verify pinout compatibility and electrical characteristics before substitution.
