The main function of TD321SCAN/TD521SCAN series is to convert TTL / CMOS level into isolated CANbus diferential level signals. The use of lc integrated technology allows for power isolation, signalisolation, CAN transceiver and bus protection all in one single CAN bus transceiver module, whichwithstands an isolation test voltage of 3000VDC. Also, they can easily be embedded in the user's endequipment, to achieve fully functional CAN bus network connectivity. The products are using pick andplace SMD packaging technology, thus enabling the use of fully automated processing
