The main function of TD301DCANHEH / TD501DCANHE series is to convert TTL / CMOS level intoisolated CAN bus diferential level signals. The use of lC integrated technology allows for power isolationsignal isolation, CAN transceiver and bus protection all in one single CAN bus transceiver module, whichwithstands an isolation test voltage of 3000VDC. The internal components are highly integrated, with lowelectromagnetic radiation and high immunity to electromagnetic interference, which improve the capablityof surge protection and simplify the application circuits. Also, they can easily be embedded in the user'send equipment, to achieve fully functional CAN bus network connectivity.
