5V Voltage Supply, High Speed CAN Bus Transceiver - SCM34xxASA
Mornsun new SCM34xxASA series contains three high reliable CAN Bus transceivers: SCM3421ASA(slope control mode), SCM3422ASA(ultra low standby current mode), SCM3423ASA(low-current transmission disable silent mode).

CAN Bus features strong real-time performance, long transmission distance, strong anti-interference ability and data guarantee arrival. The Bus withstand voltage of SCM34xxASA series is up to -40V~40V(SCM3421ASA is -36V~36V), and it has high electromagnetic immunity, ultra low electromagnetic emissions, and bus pins protected against transients and overheat protection.

Widely used in applications of IoT, industrial electronics, automotive electronics.
