74F583SC

Overview

The Fairchild Semiconductor 74F583SC is a 4-bit binary adder/subtractor integrated circuit belonging to the F/FAST logic series. It operates on TTL voltage levels and is housed in a 16-pin Small Outline Integrated Circuit (SOIC) package with a width of 0.150 inches. The device supports BCD addition and permits ripple carry cascading for multi-bit arithmetic operations. It functions within a standard temperature range, providing reliable digital logic processing for arithmetic applications.

Feature Summary

• Performs 4-bit binary addition and subtraction operations using TTL-compatible logic levels.
• Supports Binary Coded Decimal (BCD) addition functionality.
• Enables ripple carry cascading to expand arithmetic capabilities across multiple units.

Applications

• Digital arithmetic logic units requiring 4-bit calculation
• BCD counting and conversion circuits
• Cascaded multi-bit adder systems

Procurement Notes

Verify the specific suffix 'SC' against official Fairchild or onsemi documentation to confirm the SOIC-16 plastic package variant. Ensure compatibility with existing TTL logic families and operating voltage requirements before integration. Confirm lead-free status and RoHS compliance based on the manufacturing date code and current regulatory standards.

Selection Notes

Select this component when a dedicated 4-bit arithmetic solution is required within the F/FAST speed class. It is suitable for designs needing BCD support and cascading capabilities. Compare propagation delays and power consumption against other F-series variants if performance optimization is critical for the specific application environment.

Part Context

This part belongs to the 74F series, known for high-speed operation compared to standard 74LS logic. The 74F583 specifically addresses arithmetic needs, distinguishing itself from general-purpose gates. It shares functional similarities with the 74F283 but may differ in packaging or specific electrical characteristics defined by the manufacturer's datasheet.

Replacement Considerations

Check for direct equivalents such as the 74F583DC (ceramic DIP) or 74F583QC (plastic LCC) if pinout compatibility allows. Verify that substitute parts maintain the same F/FAST series speed and TTL voltage specifications to ensure seamless system integration without redesign.
