Pinout

Pin Name Type Function
1 TXD1 input Transmitter data input for transceiver 1: low drives CANH1/CANL1 dominant and high drives them recessive, with an internal pull-up of nominal 33 kΩ to VDDX.
2 VSS1 power_in Ground supply pin for transceiver 1.
3 VDD1 power_in Positive supply pin for transceiver 1, supplying its transmitter and receiver including the wake-up receiver; VDDX range is 4.5 V to 5.5 V with a typical undervoltage threshold of 4 V.
4 RXD1 output CMOS-compatible receive data output for transceiver 1 that is high in the recessive state and low in the dominant state, supplied by VDD1.
5 TXD2 input Transmitter data input for transceiver 2: low drives CANH2/CANL2 dominant and high drives them recessive, with an internal pull-up of nominal 33 kΩ to VDDX.
6 VSS2 power_in Ground supply pin for transceiver 2.
7 VDD2 power_in Positive supply pin for transceiver 2, supplying its transmitter and receiver including the wake-up receiver; VDDX range is 4.5 V to 5.5 V with a typical undervoltage threshold of 4 V.
8 RXD2 output CMOS-compatible receive data output for transceiver 2 that is high in the recessive state and low in the dominant state, supplied by VDD2.
9 CANL2 bidirectional CAN low-level bus line for transceiver 2, which disconnects from the bus when the device is not powered.
10 CANH2 bidirectional CAN high-level bus line for transceiver 2, which disconnects from the bus when the device is not powered.
11 STBY2 input Standby mode input for transceiver 2 (active-high): high selects Standby and low selects Normal mode, with an internal pull-up to VDDX of typical 660 kΩ.
12 CANL1 bidirectional CAN low-level bus line for transceiver 1, which disconnects from the bus when the device is not powered.
13 CANH1 bidirectional CAN high-level bus line for transceiver 1, which disconnects from the bus when the device is not powered.
14 STBY1 input Standby mode input for transceiver 1 (active-high): high selects Standby and low selects Normal mode, with an internal pull-up to VDDX of typical 660 kΩ.
