SN74LS85D Datasheet

Logic - Comparators


The SN74LS85D is a 4-Bit Magnitude Camparator which compares two 4-bit words (A, B), each word having four Parallel Inputs (A0 &ndash;A3, B0 &ndash;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: &ldquo;A greater than B&rdquo; (OA > B), &ldquo;A less than B&rdquo; (OA < B), &ldquo;A equal to B&rdquo; (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.Refer to Applications section of data sheet for high speed method of comparing large words. SN74LS85D Features &bull; Easily Expandable&bull; Binary or BCD Comparison&bull; OA > B, OA < B, and OA = B Outputs Available
