74LS85 4-bit magnitude comparators perform comparison of straight binary or BCD codes. Three fully-decoded decisions about two, 4-bit words (A, B) are made and are externally available at three outputs. These devices are fully expandable to any number of bits without external gates. Words of greater length may be compared by connecting comparators in cascade. The A>B, A

NOTE: HC version is the high speed CMOS version which we may supply due to availability. It is fully compatible with LS version and one to one replaceable (not vice versa as HC version has more features)
