SN75172N Description

The SN75172N from Texas Instruments is a quad differential line driver designed for RS422 and RS485 communication protocols. Housed in a 16-pin DIP (Through Hole) package, this active component operates within a 4.75V to 5.25V supply range and is rated for 0°C to 70°C industrial temperatures. As a 4/0 (4 drivers, 0 receivers) configuration, it excels in unidirectional data transmission, making it ideal for applications requiring robust signal integrity over long distances. The device is ROHS3 compliant, REACH unaffected, and carries an EAR99 ECCN classification, ensuring global compatibility. Its Moisture Sensitivity Level (MSL) is "Not Applicable," simplifying storage and handling.
