| Description | The SN65176BDR is a differential bus transceiver designed for bidirectional data communication on multipoint RS-485 and RS-422 networks. It operates from a single 5V supply and supports data rates up to 10 Mbps, enabling reliable high-speed communication over long distances. The device features a half-duplex configuration with separate driver and receiver enable controls, allowing flexible bus management. It provides a wide common-mode input voltage range of -7V to +12V and supports up to 32 nodes on the same bus. The transceiver offers low supply current typically around 70 mA during operation and includes thermal shutdown and short-circuit protection for enhanced reliability. It has a receiver input sensitivity of ±200 mV and provides high noise immunity for robust performance in industrial environments. Operating temperature range is 0°C to +70°C, and the SOIC-8 package enables compact surface-mount design. It is widely used in industrial automation, motor control, building control systems, and long-distance communication interfaces. |

The SN65176B and SN75176B differential bus transceivers are designed for bidirectional data communication on multipoint bus transmission lines. They are designed for balanced transmission lines and meet ANSI Standards TIA/EIA-422-B and TIA/ EIA-485-A and ITU Recommendations V.11 and X.27.
The SN65176B and SN75176B devices combine 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, 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 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 common-mode voltage ranges, making the device suitable for party- line applications.
The driver is designed for up to 60 mA of sink or source current. The driver features positive and negative current limiting and thermal shutdownfor protection from line-fault conditions. Thermalshutdown is designed to occur at a junctiontemperature of approximately 150°C. The receiverfeatures a minimum input impedance of 12 kΩ, an input sensitivity of ±200 mV, and a typical inputhysteresis of 50 mV.
