7.11

Wake up input (INH)

The voltages are referred to GND and currents are assumed positive, when the current

flows into the pin. 6V < VS < 18V; Tj = -40 to 130 °C, unless otherwise specified.

7.12

LIN

Compatible to Lin 2.1 for Baud rates up to 20 kBit/s

The voltages are referred to GND and currents are assumed positive, when the current

flows into the pin.

6V < VS < 18V; 4.8V < V1 < 5.2V; Tj = -40°C...130°C, unless otherwise specified.
