SN65LBC172ADW Description

Short technical summary and product information.

The SN65LBC172ADW from Texas Instruments is a quad differential line driver optimized for balanced multipoint bus transmission at signaling rates up to 30 Mbps. It is designed for TIA/EIA-485, TIA/EIA-422, and ISO 8482 applications, suitable for use with printed circuit board traces, backplanes, and cables.

 

This transceiver features drivers with current limiting and thermal shutdown circuitry, making it robust for high-speed multipoint data transfer in noisy environments. It operates over a wide temperature range of -40°C to 85°C and requires a supply voltage between 4.75V and 5.25V. The device is available in a 20-SOIC package.

 

Each driver has a 3-state output that goes to a high-impedance state when disabled or powered off, reducing system load. The G and G inputs allow for driver enable control using either positive or negative logic. This design ensures glitch-free operation during power-up/power-down in live-insertion applications.
