Description

This circuit demonstrates the implementation of a low power, RS-485 transceiver with selectable data rate and flexible I/O logic levels. A dual-output LDO allows for operation with either 1.8V or 3.3V interface logic levels. A slew rate selection pin allows for driver slew rate control, enabling low-speed data transmission (250kbps) over long distances, or high-speed data transmission (20Mbps) over shorter bus lengths.

Features
  • Interface with 1.8V or 3.3V logic levels
  • Selectable data rates: 250kbps or 20Mbps
  • Connect up to 256 nodes to the bus
  • IEC 61000-4-2 protection up to 16kV
  • IEC 61000-4-4 protection up to 4kV
