LIN is a low speed universal asynchronous receiver transmitter (UART) munication protocol that supports automotive invehicle networking. The TLIN2021-Q1 transmitter supports data rates up to 20 kbps and the receiver supports data rates up to 100 kbps for faster end-of-line programming. The TLIN2021-Q1 controls the state of the LIN bus via the TXD pin and reports the state of the bus on its open-drain RXD...
