GENERAL DESCRIPTION

Duplex universal CAN isolation transceiver TD302DCAN/
TD502DCAN series are CAN bus transceiver module with
integrated power isolation power, signal isolation chip ,and
CAN transceiver chip .
The main function of Products is to switch from logic level to
CAN bus difference level, achieve signal isolation. The product
is with constant-voltage source isolation power. It can achieve
2500 VDC electrical isolation. Products can be easily
embedded in the user equipment, achieve function of CAN bus
network connection easily.
