SN65LBC172DW Description

Short technical summary and product information.

The SN65LBC172DW from Texas Instruments is a monolithic quadruple differential line driver with three-state outputs, designed to meet EIA Standard RS-485 requirements. Optimized for balanced multipoint bus transmission, it supports data rates up to and exceeding 10 million bits per second.

 

This driver features a wide positive and negative common-mode output voltage range of -7V to 12V and operates within a supply voltage of 4.75V to 5.25V. It includes positive and negative current limiting and thermal shutdown circuitry for protection against line fault conditions, making it suitable for party-line applications in noisy environments.

 

The SN65LBC172DW is housed in a 20-SOIC package and is designed for surface mount applications. It operates across a temperature range of -40°C to 85°C, offering robustness and low power consumption.

 

Key electrical characteristics include 4 drivers with 0 receivers, a maximum signaling rate of 10 Mbps, and fault protection from -10V to 15V. The device supports 32 nodes on the bus and is not isolated.
