MC74F181N

Specialty Logic Overview

The MC74F181N is a high-performance 4-bit Arithmetic Logic Unit (ALU) belonging to the F/FAST logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a wide operating temperature range from -55°C to +125°C. The device is housed in a 24-pin Dual In-line Package (DIP). It exhibits a quiescent current of 65 mA and supports TTL-compatible inputs, enabling reliable digital processing in demanding industrial environments.

Specialty Logic Feature Summary

• Executes complex arithmetic and logical operations on 4-bit data words
• Compatible with standard TTL input voltage levels for system integration
• Rated for extended industrial temperature ranges up to 125°C

Specialty Logic Applications

• Digital signal processing systems
• Industrial control units requiring arithmetic functions
• Test and measurement equipment

Specialty Logic Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-24 package configuration. Confirm RoHS compliance status as historical F-series parts may vary by manufacturing date. Ensure the supplier provides valid traceability documentation for components intended for automotive or aerospace applications due to the extended temperature rating.

Specialty Logic Selection Notes

Select this component when a dedicated 4-bit ALU is required rather than implementing logic gates manually. Consider the 65 mA quiescent current against power budget constraints. Verify that the DIP-24 footprint matches the target PCB design compared to surface-mount alternatives like the DR2G variant.

Specialty Logic Part Context

This part belongs to onsemi's specialty logic portfolio, specifically the F/FAST series known for high-speed performance. It serves as a fundamental building block for arithmetic operations in legacy and robust digital designs, distinct from general-purpose gate arrays or microprocessors.

Specialty Logic Replacement Considerations

The MC74F181DR2G offers identical electrical functionality in a surface-mount SOIC-24 package. Cross-reference with other manufacturers' 74F181 equivalents ensuring pin compatibility and voltage tolerance alignment.
