Key Features
- B3); A3, B3 being the most significant inputs. Operation is not restricted to binary codes, the device will work with any monotonic code. Three Outputs are provided: “A greater than B” (OA > B), “A less than B” (OA < B), “A equal to B” (OA = B). Three Expander Inputs, IA > B, IA < B, IA = B, allow cascading without external gates. For proper compare operation, the Expander Inputs to the least significant position must be connected as follows: IA < B= IA > B = L, IA = B = H. For serial (ripple) expansion, the OA > B, OA < B and OA = B Outputs are connected respectively to the IA > B, IA < B, and IA = B Inputs of the next most significant comparator, as shown in Figure 1.
