CTM8250 is a general-purpose CAN transceiver chip with isolation, which integrates all necessary CAN isolation and transceiver devices on a chip of less than 3 square centimeters. The chip converts the logic level of the CAN controller to the differential level of the CAN bus and has a DC 2500V isolation function. It complies with the ISO 11898 standard and can interoperate with other CAN transceiver products that comply with the ISO 11898 standard.
The CTM8250 is an isolated CAN transceiver chip that converts CAN controller logic levels to differential bus signals while providing up to 2500 V DC isolation. It complies with ISO 11898 and supports data rates up to 1 Mbit/s, making it suitable for automotive, industrial and instrumentation applications.
The document includes functional overview, pin definitions, electrical specifications, mechanical dimensions, circuit connection diagrams, and warranty statements. It also lists ordering information and provides a typical application example showing how the chip can replace multiple discrete components in a CAN network. This manual is written in Chinese.
