WebIf CANH and CANL are shorted to a supply and the transceiver is not able to overdrive the supply, the receiver will always see a fixed signal on the CAN bus. When the common-mode voltage exceeds the driver's common-mode range (-5V to +10V), the driver is turned off. When the driver is off, the CANH/CANL output will not reflect the signal on TXD ... Webon the same CANH and CANL pins as the transmit occurs. These states are output as logic levels on the RXD pin for the CAN protocol controller to receive CAN frames. …
