The SN65LBC170DWR is a robust, high-speed, low-power differential line driver and receiver pair designed by Texas Instruments to operate using the TIA/EIA-485 standard. This integrated circuit is specifically tailored for bidirectional communication on multipoint bus transmission lines, making it an ideal choice for industrial network applications such as factory automation, building automation, and process control systems.

Key Features

• Compatibility: Conforms to the TIA/EIA-485 (RS-485) standard, ensuring interoperability with a wide range of network devices.
• Integrated Protection: Features robust bus-pin ESD protection and an integrated fail-safe feature that guarantees a high impedance receiver output when the bus is open, shorted, or idle.
• High-Speed Operation: Capable of operating at data signaling rates up to 12 Mbps, suitable for high-speed data transmission requirements.
• Wide Supply Voltage Range: Operates across a broad supply voltage range of 4.5V to 5.5V, providing flexibility in various system designs.
• Temperature Range: Designed for industrial environments with an operational temperature range of -40°C to 85°C.
• Multiple Transceivers: Up to 32 transceivers can be connected simultaneously on a bus, enabling complex network topologies.
• Package: Available in a wide-body SOIC (DWR) package, which is suitable for surface-mount technology (SMT) and provides optimal space-saving on printed circuit boards (PCBs).

Applications

The SN65LBC170DWR is designed to be a versatile component in a variety of applications.
