4-Bit Magnitude Comparators
General Description
These 4-bit magnitude comparators perform comparison of have a high-level voltage applied to the A e B input The
straight binary or BCD codes Three fully-decoded decisions cascading paths are implemented with only a two-gate-level
about two 4-bit words (A B) are made and are externally delay to reduce overall comparison times for long words
available at three out
