Product Overview

The SN65HVD1176D is a PROFIBUS RS-485 Transceiver with characteristics optimized for use in PROFIBUS (EN 50170) applications. The driver output differential voltage exceeds the PROFIBUS requirements of 2.1V with a 54R load. A signalling rate of up to 40Mbps allows technology growth to high data-transfer speeds. The low bus capacitance provides low signal distortion. The SN65HVD1176 devices 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, which allows 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 are in high impedance when the supply voltage is below 2.5V to prevent bus disturbance during power cycling or during live insertion to the bus.
  • Optimized for PROFIBUS networks
  • ESD protection exceeds ±10kV HBM
  • Fail-safe receiver for bus open, short, idle
  • Low skew during output transitions and driver enabling and disabling
  • Common-mode rejection up to 50MHz
  • Short-circuit current limit
  • Hot swap capable
  • Thermal shutdown protection
  • Green product and no Sb/Br


Automation & Process Control, Communications & Networking


This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
