SN75ALS171DW TI RS-485 Transceiver | 20-SOIC | 5V, 30Mbps, Half-Duplex

Product Overview

The SN75ALS171DW from Texas Instruments is a high-speed, low-power RS-485/RS-422 differential bus transceiver designed for bidirectional data communication on multipoint bus transmission lines. It operates from a single 5V supply and features a driver output capability of up to 30 Mbps, making it suitable for high-speed industrial networks. The device is housed in a 20-pin SOIC package (DW) and offers half-duplex communication with a 1/8 unit load, allowing up to 256 transceivers on the bus. It includes thermal shutdown protection and is specified for operation from -40°C to +85°C.
