ST3232CDR RS-232 Transceiver IC – SOIC-16 – STMicroelectronics

The ST3232CDR RS-232 Transceiver IC from STMicroelectronics is a high-performance, low-power communication interface IC designed for EIA/TIA-232 and V.28/V.24 serial communication standards. Operating from a 1V to 5V supply range, this device delivers true RS-232 signal levels using its proprietary low-dropout transmitter output stage.

With a guaranteed 300 kbps data rate, 6 V/µs slew rate, and an output voltage swing of ±5.4V, the ST3232CDR ensures reliable high-speed communication in industrial, embedded, and consumer applications. The IC requires only four 0.1 µF external capacitors when used with a 3V supply, enabling a compact and efficient design. Its SOIC-16 package provides ease of integration across a variety of PCB layouts.
