XD74LS83 – 4-Bit Binary Full Adder – Xinluda

The XD74LS83 from Xinluda is a 4-bit binary full adder with internal carry look-ahead, part of the 74LS TTL logic family, supplied in a 16-pin DIP package. Available for RFQ through Pacific Component Xchange.

The XD74LS83 is a 4-bit binary full adder manufactured by Xinluda, functionally compatible with the industry-standard 74LS83 / 74LS83A from the 74LS low-power Schottky TTL logic family. It performs the addition of two 4-bit binary words, accepting a carry input and generating four sum outputs plus a carry output. An internal carry look-ahead (fast carry) structure minimizes the carry propagation delay, making the device well suited to high-speed arithmetic and cascaded multi-stage adder designs.

Key Features

• 4-bit binary full adder with internal carry look-ahead (fast carry)
• Adds two 4-bit binary words (A1-A4, B1-B4) plus carry input (C0)
• Provides four sum outputs (S1-S4) and a carry output (C4)
• 74LS (low-power Schottky TTL) logic family
• Standard 5 V supply operation
• Operating temperature range 0 C to +70 C
• 16-pin DIP (DIP-16) through-hole package
• Drop-in functional equivalent to standard 74LS83 / SN74LS83A devices

Applications

• Arithmetic logic and adder circuits in legacy TTL systems
• Cascaded multi-bit binary addition (chaining for 8-bit, 16-bit and wider words)
• Address and offset calculation in discrete-logic designs
• Educational and laboratory digital-logic projects
• Repair and maintenance of legacy industrial and instrumentation boards
