Each word has four parallel inputs (A0 to A3 and B0 to B3); A3 and B3 being the most significant inputs. Three outputs are provided; A greater than B (OA > B), A less than B (OA < B) and A equal to B (OA = B). Three expander inputs (IA > B, IA < B and IA = B) allow cascading of the devices without external gates. HEF4585B MSI For proper compare operation the expander inputs to the least significant position must be connected as follow.
