CD4063BMS is a 4-bit magnitude comparator designed for use in computer and logic applications that require the comparison of two 4-bit words. This logic circuit determines whether one 4-bit word (Binary or BCD) is less than, equal to, or greater than a second 4-bit word. The CD4063BMS has eight comparing inputs (A3, B3, through A0, B0), three outputs (A < B, A = B, A > B) and three cascading inputs (A < B, A = B, A > B) that permit systems designers to expand the comparator function to 8, 12, 16. . . 4N bits. When a single CD4063BMS is used, the cascading inputs are connected as follows: (A < B) = low, (A = B) = high, (A > B) = low. For words longer than 4 bits, CD4063BMS devices may be cascaded by connecting the outputs of the less significant comparator to the corresponding cascading inputs of the more significant comparator. Cascading inputs (A < B, A = B, and A > B) on the least significant comparator are connected to a low, a high, and a low level, respectively.
