SN75ALS1177NSR TI RS-485 Transceiver | 16-SO | 5V, 30Mbps, Half-Duplex

Product Overview

The SN75ALS1177NSR 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 differential output capable of driving up to 32 unit loads. The device is available in a 16-pin SOIC package (NSR suffix) and is specified for industrial temperature range (-40°C to +85°C). With a signaling rate of up to 30 Mbps, it is ideal for high-speed data transmission in noisy environments.
