74F181SPC

Overview

The Fairchild Semiconductor 74F181SPC is a 4-bit Arithmetic Logic Unit (ALU) belonging to the F/FAST logic series. It operates on TTL technology with a nominal supply voltage of 5 V and a range of 4.5V to 5.5V. The device is housed in a 24-pin Plastic Dual In-line Package (PDIP). It supports synchronous operation and performs all possible 16 logic operations on two variables. The component is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Executes all 16 possible logic operations on two variables
• Supports synchronous operation modes
• Utilizes F/FAST TTL technology for digital processing

Applications

• Digital electronics logic circuits
• Arithmetic processing units
• General-purpose logic applications

Procurement Notes

Verify the manufacturer source, as documentation lists both Fairchild Semiconductor and National Semiconductor (TI) for this part number. Confirm the package type matches the specific suffix 'SPC' (PDIP) rather than other variants like FC (Flatpack). Ensure the RoHS status aligns with project requirements, as some related datasheets indicate non-compliance for similar packaging types.

Selection Notes

Select this component when a 4-bit ALU capable of performing all 16 logic functions is required. It is suitable for designs needing synchronous operation and standard TTL voltage levels. Consider the 24-pin PDIP package constraints for board layout. Verify compatibility with the F/FAST series characteristics regarding speed and power consumption relative to other logic families.

Part Context

This component is part of the 74F181 family of arithmetic logic units. Variants such as 74F181FC exist with different packaging (CDFP24 Flatpack) and potentially different regulatory certifications. The 74F181SPC specifically denotes the plastic dual in-line package configuration manufactured by Fairchild Semiconductor or its successor entities.
