Overview
The ST3232EBPR, produced by STMicroelectronics, is a 3 V powered EIA/TIA-232 and V.28/V.24 communication interface. This device is designed with low power requirements and high data-rate capabilities, making it suitable for a variety of applications. It features enhanced electrostatic discharge (ESD) protection up to ±15 kV using the human body model and ±8 kV using IEC 1000-4-2 contact discharge. The ST3232EBPR includes a proprietary low-dropout transmitter output stage that ensures true RS-232 performance from 3 to 5 V supplies, utilizing a dual charge pump that requires only four small 0.1 µF external capacitors.
