It consists of a driver and a receiver, both of which can be enabled and disabled independently. When both are disabled, the driver and receiver emit a high-resistance state.
The SCM3406ASA has only 1/8 the standard load, allowing up to 256 nodes on a bus, making it suitable for data transmission up to 10 Mbps. Furthermore, the SCM3406ASA features failover and short-circuit protection (current limiting).
Applications:
It can be widely used in the fields of industrial automation, building automation, smart electricity meters, remote signal interaction, transmission, etc.
Typical circuit 1: Half-duplex network topology
Typical circuit 2: Typical transceiver design
Typical circuit 3: RS485 protocol transceiver integrating power isolation, signal isolation, RS485 communication, and bus protection
