Pin Configuration (top view)

Note: The pin configuration of the TLE7269G is pin compatible to the devices TLE7259G and TLE7259-2GE/GU.

In comparison to the TLE7259G and the TLE 7259-2GE/GU, no pull up resistors on the RxD pins are

required for the TLE7269G. Details can be found inside the “Pin Compatibility to the Single LIN

Transceivers” on Page 28.
