TLE9351VSJXTMA1

Infineon Technologies · CAN ICs · SOIC-8

TLE9351VSJXTMA1 from Infineon Technologies, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 TxD input Transmit data input with internal pull-up to VIO; a low level drives the bus dominant, and a continuous low longer than tTxD triggers the TxD time-out.
2 GND power_in Ground.
3 VCC power_in Transmitter supply voltage (abs max -0.3 to 6.0 V) with a recommended 1 µF decoupling capacitor to GND; VCC can be turned off in stand-by mode.
4 RxD output Receive data output that is low in the dominant state, limited to ±5 mA output current and VIO+0.3 V max.
5 VIO power_in Digital supply input (abs max -0.3 to 6.0 V) that adapts logic levels to the microcontroller supply and supplies the low-power receiver, with a recommended 100 nF decoupling capacitor to GND.
6 CANL bidirectional CAN bus low level input/output, short circuit proof to GND and supply, with DC voltage range of -40 to 40 V.
7 CANH bidirectional CAN bus high level input/output, short circuit proof to GND and supply, with DC voltage range of -40 to 40 V.
8 STB input Stand-by mode control input with internal pull-up to VIO; low selects normal-operating mode.
