5.5.10

Wake up inputs (WU1 ... WU3)

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

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

5.5.11

High speed CAN transceiver(d)

Selective wake functionality according to ISO 11898-6

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

flows into the pin. 6 V < VS < 18 V; 4.8 V < VCANSUP.< 5.2 V; Tjunction = -40°C to 130°C,

unless otherwise specified. -12 V = (CANH + CANL) / 2 = 12 V.
