The devices are designed for balanced transmission lines and meet TIA/EIA-422-B, TIA/EIA-485-A, and ITU Remendations V.11 and X.27. The SN65ALS176 and SN75ALS176 series bine a 3-state, differential line driver and a differential input line receiver, both of which operate from a single 5V power supply. The driver and receiver have activehigh and active-low enables, respectively, that can be connected together externally to function as a direction control. The driver differential outputs and the receiver differential inputs are connected internally to form a differential input/output (I/O) bus port that is designed to offer minimum loading to the bus when the driver is disabled or VCC = 0. This port features wide positive and negative mon-mode voltage ranges, making the device suitable for partyline applications. The SN65ALS176 is characterized for operation from - 40°C to 85°C. The SN75ALS176 series is characterized for operation from 0°C to 70°C.
