isolation

transceiver

TD301DCANH3/TD501DCANH3

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, and has the function of

ESD protection. Products can be easily embedded in the user

equipment, achieve function of CAN bus network connection

easily.
