In transmit mode, the TXD input drives the LIN bus pin low (dominant) when TXD is low, and the bus is pulled high (recessive) via an external pull-up resistor when TXD is high. In receive mode, the LIN bus voltage level is compared against thresholds to generate the RXD output. The built-in LIN slave terminator eliminates the need for an external series diode and resistor for slave nodes. Sleep mode powers down most internal circuitry while maintaining the ability to wake on LIN bus activity, reducing current to just 3\u03bcA.","pin_description":"
