ISO1176 - RS-485 Profibus Transceiver

General Description

The ISO1176 device is an isolated differential line transceiver designed for use in PROFIBUS applications.

The device is ideal for long transmission lines because the ground loop is broken to provide for operation with a much larger common-mode voltage range.

Key Features

  • 1 Meets or Exceeds the Requirements of EN 50170 and TIA/EIA-485-A.
  • Signaling Rates up to 40 Mbps.
  • Differential Output Exceeds 2.1 V (54-Ω Load).
  • Low Bus Capacitance.
  • 10 pF (Maximum).
  • Up to 160 Transceivers on a Bus.
  • 50 kV/μs Typical Transient Immunity.
  • Fail-Safe Receiver for Bus Open, Short, Idle.
  • 3.3-V Inputs are 5-V Tolerant.
  • Bus-Pin ESD Protection.
  • 16-kV HBM Between Bus Pins and GND2.
  • 6.
