Operation is not restricted to binary codes, the device will work with any monotonic code. Three Outputs are provided: “A greater than B” (OA\u0026gt;B), “A less than B” (OA\u0026lt;B), “A equal to B” (OA=B). Three Expander Inputs, IA\u0026gt;B, IA\u0026lt;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\u0026lt;B= IA\u0026gt;B = L, IA=B = H. For serial (ripple) expansion, the OA\u0026gt;B, OAB, IA\u0026lt;B, and IA=B Inputs of the next most significant comparator, as shown in Figure 1. Refer to the Applications section of the datasheet for the high-speed method of comparing large words. The Truth Table on the following page describes the operation of the SN54\/74LS85 under all possible logic conditions. The upper 11 lines describe the normal operation under all conditions that will occur in a single device or a series expansion scheme. The lower five lines describe the operation under abnormal conditions on the cascading inputs. These conditions occur when the parallel expansion technique is used.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eEasily Expandable\u003c\/li\u003e\n\u003cli\u003eBinary or BCD Comparison\u003c\/li\u003e\n\u003cli\u003eOA\u0026gt;B, OA\u0026lt;B, and OA=B Outputs Available\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"electro robo store","offers":[{"title":"Default Title","offer_id":52741107712276,"sku":"MT0711","price":33.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0979\/6590\/0052\/files\/74_b955a41d-4a62-4cda-804f-478e7b834aff.jpg?v=1783168025","url":"https:\/\/electro-robo.com\/products\/74ls85-4-bit-magnitude-comparator-ic-7485-ic-dip-16-package","provider":"Electro Robo Store","version":"1.0","type":"link"}
