Integrated isolated 3.3V/5V power, the Chiplet RS485/422 Transceiver - R4 series

Mornsun Chiplet SiP package R4 series is designed for data bus networks, meeting the various market requirements, such as the highly integrated system. This time, Mornsun launched a series of products, including:

• Half-duplex RS485: TD(H)341S485H(S), TD(H)541S485H-A series

• Full-duplex RS422: TD(H)341S485S-F(F1/FT) series

• High-rate digital isolator: TDx41S-4xxx series

Duplexer type

• In the process of data transmission, it generally transmits in two directions. 

• Full-duplex allows the data transmitted in both directions. Similar to a phone call, the voices of both sides can be heard from each other. 

• While half-duplex is similar to speaking on a walkie-talkie, only one side of the voice is allowed to be transmitted to the other side at a time. 

• The outstanding advantage of a full-duplex over a half-duplex is that the transmission mode can be used for point-to-point connections without conflict.

Based on the on-sale half-duplex products, MORNSUN expands and develops new products that can meet the use of various bus networks so that customers can select flexibly for different working conditions.
