The SN65176B and SN75176B are designed for balanced transmission lines and meet ANSI Standards TIA/EIA-422-B and TIA/EIA-485-A and ITU Remendations V.11 and X.27. The SN65176B and SN75176B devices 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 has a active-high enable and the receiver has an active-low enable, that can connect together externally to function as a direction control. The driver differential outputs and the receiver differential inputs are connected internally to form differential input/output (I/O) bus ports that are designed to offer minimum loading to the bus when the driver is disabled or VCC = 0. These ports feature wide positive and negative mon-mode voltage ranges, making the...
