74F583PC

Overview

The Fairchild Semiconductor 74F583PC is a high-speed 4-bit BCD full adder belonging to the F/FAST series. It accepts two 4-bit decimal numbers and a carry input, utilizing internal carry lookahead for rapid computation. The device operates on a 5 V supply within a 0°C to 70°C temperature range. It is housed in a 16-pin ceramic DIP package with glass-sealed construction. This TTL logic component supports ripple carry cascading for multi-digit arithmetic operations.

Feature Summary

• High-speed binary full adder functionality with internal carry lookahead architecture
• Supports Binary Coded Decimal (BCD) addition of two 4-bit decimal numbers
• Enables ripple carry cascading for extended arithmetic applications

Applications

• Digital arithmetic processing units requiring BCD calculation
• Cascaded multi-digit decimal addition systems
• TTL-based digital logic circuit designs

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm package integrity and pin alignment upon receipt. Check for lead-free compliance status if required by specific environmental regulations. Ensure storage conditions maintain ceramic package stability. Validate part markings against official datasheet specifications before integration into production lines.

Selection Notes

Select this component when high-speed BCD addition is required within standard TTL voltage levels. The ceramic DIP package offers robustness for through-hole mounting in industrial environments. Consider the internal carry lookahead feature for performance-critical timing constraints. Verify compatibility with existing 5V logic families in the target system design.

Part Context

This component belongs to the Fairchild 74F series, designed for fast switching speeds in TTL applications. The 74F583 specifically addresses decimal arithmetic needs using BCD encoding. It serves as a fundamental building block for digital counters and calculators. The ceramic packaging distinguishes it from plastic variants, offering enhanced durability.

Replacement Considerations

Equivalent parts include other 74F583 variants such as the DC (ceramic DIP) or QC (plastic LCC) versions. Cross-reference pinouts and electrical characteristics carefully. Verify that substitute components maintain the same BCD full adder functionality and speed grades.
