6.2 Galvanic Isolation
The interface pins TxD, RxD and TSTOUT_TW are prepared for galvanic isolation with
optocouplers. The interface output pins TxD and TSTOUT_TW provide a driver current of
5 mA, thus the transmitting diode of an optocoupler can be connected directly. The interface
input pin RxD is implemented as a Schmitt Trigger. There are no additional level shifters
after the output of the optocoupler necessary.
In Normal Mode it is possible to recognize a reset via TxD without an additional optocoupler.
Please refer to 3.2.2. A busvoltage breakdown can also be monitored if in quiescent state
the transmitting diode belonging to TxD is active.
