SN75C189ADB TI RS-232 Transceiver | 4 Drivers, 0 Receivers | 5V Supply, 30V/us Slew Rate

Product Overview

The SN75C189ADB is a quad RS-232 line driver from Texas Instruments, designed for serial communication in industrial and commercial applications. It operates from a single 5V power supply and features four independent drivers that convert TTL/CMOS logic levels to RS-232 voltage levels. The device is housed in a 16-pin SSOP package, offering a compact solution for space-constrained designs. With a slew rate of 30V/µs and data rates up to 120 kbps, it ensures reliable data transmission over moderate cable lengths. The SN75C189ADB is characterized for operation from 0°C to 70°C, making it suitable for typical commercial environments.
