7.1
ESD Robustness according to IEC61000-4-2
Test for ESD robustness according to IEC61000-4-2 “Gun test” (150 pF, 330 Ω) have been performed. The results
and test conditions are available in a separate test report.

Pin Compatibility to other LIN Transceivers
The LIN Transceiver TLE7259-2GU is pin and function compatible to the Single LIN Transceivers like the
TLE7259G, the TLE7259-2GE and other single LIN Transceivers on the market. The TLE7259-2GU has no V_IO
supply pin. Therefore the TLE7259-2GU needs a pull-up resistor to the external microcontroller supply. The
TLE7259-2GU can also be used on a PCB design for the Twin LIN TLE7269G. Since the TLE7269G doesn’t need
a pull-up resistor on the RxD pin, a pull-up resistor to the external microcontroller needs to be added to get the
same functionality.
