SN65C189D TI RS-232 Transceiver | 5V, 250kbps, 2 Drivers/2 Receivers

Product Overview

The SN65C189D from Texas Instruments is a dual driver and dual receiver RS-232 interface IC designed for serial communication in industrial and commercial applications. It operates from a single 5V power supply and features a low-power shutdown mode. The device meets the requirements of TIA/EIA-232-F and ITU V.28 standards, ensuring reliable data transmission up to 250 kbps. With integrated charge pump circuitry, it generates the necessary RS-232 voltage levels (±5V to ±15V) from a single 5V supply, simplifying power supply design.
