3.1 Pin Assignment
Figure 2 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
IO
power supply and needs a pull up resistor at the RxD pin. Details can be found in the chapter “Pin
Compatibility to other LIN Transceivers” on Page 24.
