The CA-IF1021x-Q1 family of device is Local Interconnect Network (LIN) transceiver with integrated wake-up and protection features for automotive applications. LIN is lowspeed universal asynchronous receiver transmitter (UART) communication protocol used to support in-vehicle networks. The CA-IF1021x-Q1 transceiver controls the LIN bus state via the TXD input and reports the bus state on its open-drain output RXD between the protocol controller and physical LIN networks.
