SN75119D TI Line Driver/Receiver | 8-SOIC | Single Differential, 5V

Product Overview

The SN75119D is a single differential line driver and receiver from Texas Instruments, designed for bidirectional data communication over balanced transmission lines. It complies with ANSI Standards EIA/TIA-422-B and RS-485, making it suitable for long-haul, high-noise industrial environments. The device operates from a single 5V supply and features a wide common-mode voltage range, high input impedance, and thermal shutdown protection. Housed in an 8-pin SOIC package, it offers a compact solution for point-to-point or multipoint bus applications.
