Product Introduction

Overview

The ADM232LJR is an integrated circuit (IC) transceiver designed for RS-232 serial communications, manufactured by Analog Devices, Inc. This component is part of the ADM2xx family, which is intended for all EIA-232-E and V.28 communications interfaces. The ADM232LJR is particularly useful in applications where ±12 V is not available, as it operates from a single 5 V power supply.

The transceiver features full-duplex operation, supporting two drivers and two receivers, and is capable of data rates up to 120 Kbps. It is packaged in a compact 16-SOIC surface mount design, making it easy to integrate into various electronic devices and systems.
