The main function ofTD322DCAN/ TD522DCAN 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 two-port isolation test voltage of 2500VDC and channel isolation test voltage of 1500VDCAlso, they can easily be embedded in the user's end equipment, to achieve fully functional CAN busnetwork connectivity.
