Here are some more examples that further demonstrate the LTC2876 and LTC2877’s performance. The first graph shows that the typical driver differential output voltage never exceeds the 7V PROFIBUS limit, regardless of what kind of supply or load is used, and that operation is guaranteed down to 3V for RS485. The second graph shows that the power supply current draw at 3.3V is about half that at 5V operation, which never exceeds more than 50mA.
