The main function of TD301DCANH3 / TD501DCANH3 series is to convert TTL / CMOS level into isolatedCAN bus 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.
