They are designed for balanced transmission lines and meet ANSI Standard TIA/EIA- 485- A (RS-485) and ISO 8482:1987(E). The SN55LBC176, SN65LBC176, SN65LBC176Q, and SN75LBC176 bine a 3-state, differential line driver and a differential input line receiver, both of which operate from a single 5-V power supply. The driver and receiver have active-high and active-low enables, respectively, which can externally connect together to function as a direction control. The driver differential outputs and the receiver differential inputs connect internally to form a differential input/output (I/O) bus port that is designed to offer minimum loading to the bus whenever the driver is disabled or VCC = 0. This port Features wide positive and negative mon-mode...
