74LS85 or SN54/7485 is a 4-bit magnitude comparator of two binary format inputs. In electronics devices besides addition and subtraction comparison of binary numbers is also important to perform the operations. To solve this issue, we use TTL based comparators.

These 4-bit magnitude comparators perform comparison of straight binary or BCD codes. Three fully-decoded deci- sions about two, 4-bit words (A, B) are made and are exter- nally available at three outputs. These devices are fully expandable to any number of bits without external gates.

Jul 28, 2018 · In this project SN7485 IC is used which is a 4-bit magnitude comparator. The two 4-bit numbers are input to the IC through a DC supply via 8 position DIP switch. The result of the comparison is verified by connecting LEDs at the output pins of the IC. Components Required –.
