74F382SC

Overview

The Fairchild Semiconductor 74F382SC is a 4-bit Arithmetic Logic Unit (ALU) housed in a 20-pin Small Outline Integrated Circuit (SOIC) package. It executes three arithmetic and three logic operations on two 4-bit input words, A and B. The device features dual output enable control via Select inputs S0–S2, which also determine the specific operation mode. Designed for high-speed digital applications, it operates within a standard temperature range of 0°C to 70°C and supports synchronous data processing with a maximum operating frequency of 90 MHz.

Feature Summary

• Executes multiple arithmetic and logic functions on 4-bit binary words
• Features dual output enable control for flexible bus interfacing
• Operates at high speeds up to 90 MHz for efficient data processing

Applications

• Microprocessor-based system data paths
• Digital signal processing units requiring arithmetic operations
• Control logic circuits for embedded systems

Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor was acquired by ON Semiconductor. Confirm the package type is 20-SOIC and check for RoHS compliance status. Ensure the component matches the original Fairchild part number specifications before integration into designs.

Selection Notes

Select this component when a dedicated 4-bit ALU is required for arithmetic and logic tasks. Consider the 20-SOIC package for surface-mount assembly needs. Evaluate the 90 MHz speed capability against system timing requirements. Verify voltage levels and power consumption constraints for the target application environment.

Part Context

The 74F382 belongs to the 74F series of high-speed logic devices. This series is known for improved performance over standard TTL equivalents. The SC suffix denotes the 20-lead SOIC package variant. These components are widely used in digital systems requiring reliable arithmetic processing capabilities.

Replacement Considerations

Compatible substitutes include the NXP 74F382. Verify pin compatibility and electrical characteristics before substitution. Ensure the replacement maintains the same 4-bit ALU functionality and package dimensions.
