SN75LBC172N Description

Short technical summary and product information.

The SN75LBC172N from Texas Instruments is a monolithic quadruple differential line driver with three-state outputs, designed to meet EIA Standard RS-485. This device is optimized for balanced multipoint bus transmission, supporting data rates up to and exceeding 10 million bits per second.

 

Key electrical specifications include a signaling rate of 10 Mbps, a fault protection range of -10V to 15V, and a common-mode output voltage range of -7V to 12V. It operates within a temperature range of 0°C to 70°C and requires an operating voltage of 4.75V to 5.25V. The driver consumes low power, with a maximum supply current of 7000 µA.

 

Designed for robustness and low power consumption using LinBiCMOS technology, the SN75LBC172N offers positive- and negative-current limiting and thermal shutdown circuitry for protection against line fault conditions. It is suitable for party-line applications in noisy environments.

 

The component is available in a 16-PDIP package and is designed for through-hole mounting. It functions interchangeably with the SN75172.
