9.2.1 Design Requirements
Example Application: Isolated Bus Node with Transient Protection
- RS-485-compliant bus interface.
- Galvanic isolation of both signal and power supply lines.
- Able to withstand surge transients up to 1 kV (per IEC 61000-4-5).
- Full control of data flow on bus in order to prevent contention (for half-duplex communication).
