7.3.3 Transmitter Timeout

The driver path incorporates a timeout feature to prevent a faulty node from occupying the bus indefinitely in a multi-drop application.

The driver stops transmitting and the outputs go high impedance if the D input does not detect an edge (either rising or falling) for longer than tTX_TIMEOUT. One of the following events brings the device back to normal operation.

  • Any edge at D input
  • Toggle MODE pin

The transmit path resumes operation within tMODE.
