The SN75ALS181NSR from Texas Instruments is a high-speed transceiver IC supporting both RS422 and RS485 serial communication standards. This device is built with advanced low-power Schottky circuitry, enabling operation at a maximum signaling rate of 25 Mbps. It features a full-duplex design, meaning it can transmit and receive data simultaneously.
Key electrical characteristics include a wide common-mode voltage range of -7V to 12V and a fault protection range of -10V to 15V. The transceiver operates from a single 5V supply (4.75V to 5.25V) and has a low supply current requirement of 30 mA maximum. It supports up to 32 nodes on the bus and offers individual driver and receiver I/O pins.
Designed for reliability, the SN75ALS181NSR includes thermal shutdown protection and driver positive/negative current limiting. It also features glitch-free power-up and power-down protection. The receiver input impedance is a minimum of 12 kΩ, with a sensitivity of ±200 mV and typical hysteresis of 60 mV.
This transceiver is available in a 14-SOIC surface mount package, measuring 5.30mm in width. It operates within a temperature range of 0°C to 70°C, making it suitable for various industrial and commercial applications requiring robust serial data communication.
