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.
The XD74LS83 is a niche logic IC with limited authorized-distributor presence. Pacific Component Xchange specializes in sourcing scarce, end-of-life, and allocation-constrained semiconductors and logic components like this one. Whether you need a handful of pieces for a repair or production volume for a legacy build, our global supplier network helps you secure authentic parts.
We focus on authenticity and traceability, offering inspection and verification to reduce counterfeit risk, plus worldwide shipping to keep your production on schedule. Because the XD74LS83 is an RFQ item, pricing and lead time are quoted per request. Contact Pacific Component Xchange today to request a quote for the XD74LS83 and let our sourcing team locate the quantity you need.
The XD74LS83 is a 4-bit binary full adder from Xinluda, part of the 74LS TTL logic family. It adds two 4-bit binary numbers using internal carry look-ahead (fast carry) and is functionally equivalent to the standard 74LS83 / 74LS83A.
The XD74LS83 is supplied in a 16-pin DIP (DIP-16) through-hole package.
Yes. The XD74LS83 is Xinluda's branded version of the industry-standard 74LS83 / SN74LS83A 4-bit binary full adder and is intended as a functional drop-in equivalent.
As a 74LS-family TTL device, the XD74LS83 operates from a standard 5 V supply over a 0 C to +70 C operating temperature range.
The XD74LS83 is a hard-to-find, request-for-quote item with limited authorized-distributor availability. Pacific Component Xchange can source it through its global supplier network - contact us to request a quote and current lead time.
Fast carry (carry look-ahead) is an internal structure that reduces the carry propagation delay between bit stages, allowing faster addition than ripple-carry adders and making it easier to cascade multiple devices for wider arithmetic.
