7483APC

Overview

The Fairchild Semiconductor 7483APC is a high-speed 4-bit binary full adder belonging to the 74S series. It accepts two 4-bit binary words (A0-A3, B0-B3) and a carry input (C0). The device features internal carry lookahead for fast operation. It is housed in a 16-pin Plastic Dual In-Line Package (PDIP-16).

Feature Summary

• High-speed 4-bit binary addition capability with internal carry lookahead logic.
• Accepts two 4-bit binary inputs and a single carry input for cascading operations.

Applications

• Digital arithmetic logic units requiring fast binary summation.
• Address calculation circuits in microprocessor systems.
• Data processing modules utilizing parallel binary addition.

Part Context

The 7483APC is part of the standard 74-series logic family, specifically the high-speed S variant. It serves as a fundamental building block for digital computation, providing reliable binary addition functionality in through-hole circuit designs.

Replacement Considerations
