Product details

Description

These 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 l B A k B and A e B outputs of a stage handling less-significant bits are connected to the corresponding inputs of the next stage handling
