SN65HVD37DR RS-485 Driver/Receiver

Texas Instruments' SN65HVD37DR combines a robust differential driver and a receiver with high noise immunity for demanding industrial applications. The driver differential outputs and the receiver differential inputs are separate pins, forming a bus port for full-duplex (four-wire) communications. The driver and receiver can be independently enabled and feature a wide common-mode voltage range, making this device suitable for multi-point applications over long cable runs. The SN65HVD37 is characterized over the temperature range of -40°C to +85°C.

  • Low-current standby mode: <1 µA Typical
  • Operational quiescent current < 1 mA
  • High receiver hysteresis for noise immunity (60 mV typical)
  • 1/8 unit-load (Up to 256 nodes on the bus)
  • Bus-pin ESD protection exceeds 15 kV HBM
  • Driver output transition times optimized for signaling rate up to 20 Mbps
  • Telecommunications equipment
  • Industrial automation
  • Process automation
  • Building automation
  • Point-of-sale (POS) terminals
  • Improved replacement for ADM3076, ADM3491, LTC2852, MAX3491 and SP3491
