The HCC/HCF4585B 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 HCC/HCF4585B 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 ... 4 N bits. When a single HCC/HCF4585B is used, the cascading inputs are connected as follows : ...
