SN75ALS1177NSR Description

Short technical summary and product information.

The SN75ALS1177NSR from Texas Instruments is a dual differential transceiver IC designed for robust bidirectional data communication on multipoint bus transmission lines. It meets TIA/EIA-422-B and TIA/EIA-485-A standards, making it suitable for long bus lines in noisy environments.

 

This transceiver features 2 drivers and 2 receivers, operating from a single 5V supply. It offers a signaling rate of up to 10 Mbps and includes fault protection ranging from -10V to 15V. The common-mode range is -7V to 12V, and it supports up to 32 nodes on the bus.

 

Packaged in a 16-SOIC (0.209", 5.30mm Width) surface-mount package, the SN75ALS1177NSR operates within a temperature range of 0°C to 70°C. Key electrical characteristics include a receiver hysteresis of 50 mV typical and a receiver input impedance of 12 kΩ minimum. Driver protection features include positive and negative current limiting and thermal shutdown.

 

Designed for applications requiring reliable data transmission over extended distances, this transceiver is a component for industrial automation, communication systems, and other embedded applications where data integrity is critical.
