XD74LS85 – 4-Bit Magnitude Comparator – Xinluda

The Xinluda XD74LS85 is a 4-bit magnitude comparator in a DIP-16 package, part of the 74LS TTL logic family. It compares two 4-bit binary or BCD words and provides three fully decoded outputs (A>B, A=B, A<B) with full cascade expandability.

The Xinluda XD74LS85 is a 4-bit magnitude comparator from the popular 74LS low-power Schottky TTL logic family, supplied in a through-hole DIP-16 package. It performs comparison of two 4-bit words of straight binary or straight BCD (8-4-2-1) code, producing three fully decoded decision outputs that indicate whether the A word is greater than, equal to, or less than the B word.

Designed for straightforward digital design, the XD74LS85 is fully expandable to any number of bits without external gates by cascading multiple devices. This makes it a dependable building block for arithmetic, control, and decision logic in legacy and maintenance-driven designs.
