A series of decoders, multiplexers, and demultiplexers of 74LS series low-power Schottky logic ICs. The 74LS series uses bipolar junction technology, coupled with Schottky diode clips to achieve the same operating speed as the original 74TTL series, but with much lower power consumption.These devices contain three independent 3-input and gates. The SN74LS85N is characterized for operation from 0°C to 70°C.
The 74LS85N is a 4-Bit Magnitude Camparator which compares two 4-bit words (A, B), each word having four Parallel Inputs (A0-A3, B0-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" (OAB, IAB = L, IA=B= H. For serial (ripple) expansion, the OA>B, OAB, IA
