It provides differential transmit and receive capability between the CAN controller and bus. Features very low EME, silent mode, TXD dominant time-out, thermal protection, and 3.3V\/5V compatible inputs. Successor to PCA82C250 with improved EME and unpowered node behavior.","working_principle":"The driver converts single-ended TXD to differential CANH\/CANL bus signals. In dominant state (TXD=low), CANH goes high and CANL goes low with ~2V differential. In recessive state (TXD=high or floating), both outputs sit at VCC\/2. The S pin selects high-speed mode (S=GND) or silent mode (S=VCC, transmitter disabled). TXD dominant time-out prevents bus lockup if TXD is stuck low (>450us typical). Thermal shutdown disables the driver at ~165 C junction temperature.","pin_description":"
