TIDA-00193, RS-485 Interface with Integrated 1.8V Level-Shift Capability

TIDA-00193, RS-485 Interface with Integrated 1.8V Level-Shift Capability. 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 (250 kbps) over long distances, or high-speed data transmission (20 Mbps) over shorter bus lengths
