... Pin Configuration Note: The pin configuration of the TLE7259-2GE is pin compatible to the devices TLE7259G, TLE7259-2GU and the Twin LIN Transceiver TLE7269G. In comparison to the TLE7269G, the TLE 7259-2GE has no separate V power supply and needs a pull up resistor at the RxD pin. Details can be found inside the chapter IO Compatibility to other LIN Transceivers” ...
