Overview
The TLIN1024-Q1, produced by Texas Instruments, is a quad Local Interconnect Network (LIN) physical layer transceiver. This device is designed to convert the LIN protocol data stream on the TXD input into a LIN bus signal using a current-limited wave-shaping driver, which reduces electromagnetic emissions (EME). It is compliant with various LIN standards, including LIN2.0, LIN2.1, LIN2.2, LIN2.2A, and ISO/DIS 17987–4.2, and conforms to SAE J2602 recommended practices for LIN. The TLIN1024-Q1 is particularly suited for automotive applications due to its AEC Q100 qualification and wide operating temperature range of –40 to 125°C.
