What is LTC2873IUFD#PBF used for?
The LTC2873IUFD#PBF is designed for industrial automation networks, motor drives, and PLCs where a single transceiver must support both RS-485 multi-drop buses and point-to-point RS-232 links without board redesign. Its switchable termination and multiprotocol capability reduce BOM cost and simplify hardware that connects field devices over long cable runs. The device is also suited for building automation controllers, test and measurement equipment, and smart metering systems operating in harsh electrical environments.

Frequently Asked Questions
What communication protocols does the LTC2873IUFD#PBF support on a single bus, and what data rates can it achieve?
The LTC2873IUFD#PBF supports RS-485, RS-422, and RS-232 protocols selectable via logic pins on a single transceiver. In RS-485/422 mode it delivers data rates up to 20 Mbps, while RS-232 mode covers standard baud rates up to several Mbps, enabling flexible protocol selection without a board redesign.
How does the switchable termination feature in this transceiver reduce external component count in RS-485 networks?
The device integrates an on-chip 120 Ω termination resistor that can be enabled or disabled by a logic pin, eliminating the need for a discrete termination resistor at the end of the RS-485 bus. This saves board space and simplifies the PCB layout in industrial multi-drop networks where proper line termination is required to prevent signal reflections at data rates above 1 Mbps.
What level of ESD protection does the LTC2873IUFD#PBF provide on its bus pins, and why does that matter for industrial deployments?
The bus pins are protected to ±15 kV using the Human Body Model, which is critical for industrial field devices where cables can accumulate large static charges during installation or operation. This level of protection reduces the risk of transceiver damage in environments with frequent hot-plugging or long cable runs connecting PLC racks to remote sensors.
