Symbol

Function

1TxD

Transmit Data Input;

Internal pull-up to VIO, “low” for dominant state.

2GND

Ground

VCC

Transmitter Supply Voltage;

100 nF decoupling capacitor to GND required,

VCC can be turned off in stand-by mode.

4RxD

Receive Data Output;

“low” in dominant state.

VIO

Digital Supply Voltage;

Supply voltage input to adapt the logical input and output voltage levels of the

transceiver to the microcontroller supply.

Supply for the low-power receiver.

100 nF decoupling capacitor to GND required.

6CANL

CAN Bus Low Level I/O;

“low” in dominant state.

7CANH

CAN Bus High Level I/O;

“high” in dominant state.

8STB

Stand-by Input;

Internal pull-up to VIO, “low” for Normal-operating mode.
