Description

The SN65HVD1176D belongs to SN65HVD1176 and SN75HVD1176 series which meet or exceed the requirements of ANSI standard TIA/EIA-485-A (RS-485) for differential data transmission across twisted-pair networks. The driver outputs and receiver inputs are tied together to form a half-duplex bus port, with one-fifth unit load, allowing up to 160 nodes on a single bus. The receiver output stays at logic high when the bus lines are shorted, left open, or when no driver is active. The driver outputs of SN65HVD1176D are in high impedance when the supply voltage is below 2.5 V to prevent bus disturbance during power cycling or during live insertion to the bus. An internal current limit protects the transceiver bus pins in short-circuit fault conditions by limiting the output current to a constant value. Thermal shutdown circuitry protects the SN65HVD1176D against damage due to excessive power dissipation caused by faulty loading and drive conditions. The SN75HVD1176 is characterized for operation at temperatures from 0°C to 70°C. The SN65HVD1176 is characterized for operation at temperatures from -40°C to 85°C. SN65HVD1176D is half-duplex differential transceivers, with characteristics optimized for use in PROFIBUS (EN 50170) applications. The driver output differential voltage exceeds the Profibus requirements of 2.1 V with a 54- load. A signaling rate of up to 40 Mbps allows technology growth to high data transfer speeds. The low bus capacitance provides low signal distortion.

The features of SN65HVD1176D can be summarized as (1)optimized for PROFIBUS networks -meets the requirements of EN 50170, -signaling rates up to 40 Mbps, -differential output exceeds 2.1 V (54 load), -low bus capacitance: 10 pF (Max); (2)meets the requirements of TIA/EIA-485-A; (3)ESD protection exceeds ±10 kV HBM; (4)failsafe receiver for bus open, short, idle; (5)up to 160 transceivers on a bus; (6)low skew during output transitions and driver enabling / disabling; (7)common-mode rejection up to 50 MHz; (8)short-circuit current limit; (9)hot swap capable; (10)thermal shutdown protection.

The absolute maximum ratings of SN65HVD1176D are (1)supply voltage(2), VCC: -0.5 V to 7 V; (2)voltage at any bus I/O terminal: -9 V to 14 V; (3)voltage input, transient pulse, A and B, (through 100, see Figure 14): -40 V to 40 V; (4)Voltage input at any D, DE or RE terminal: -0.5 V to 7 V; (5)receiver output current, IO: -10 mA to 10 mA; (6)electrostatic discharge human body model, (HBM)(3) all pins: 4 kV, bus terminals and GND: 10 kV; (7)junction temperature, TJ: 150°C.((1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the SN65HVD1176D at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values, except differential I/O bus voltages, are with respect to network ground terminal. (3) Tested in accordance with JEDEC standard 22. test method A114-A.)
