Product Introduction

Overview

The ST232BDR, produced by STMicroelectronics, is a dual driver and dual receiver device that adheres to the EIA/TIA-232 and V.28 communication standards. This component is particularly suited for applications where ±12V power is not available, as it operates on a single 5V power supply. It requires only four external capacitors (0.1μF) for operation, making it efficient for various low-power and portable applications.
