Overview
The ST232CWR is a 2 driver, 2 receiver device produced by STMicroelectronics, designed to comply with the EIA/TIA-232 and V.28 communication standards. This component is particularly suitable for applications where ±12V power is not available, as it operates using a single 5V power supply and requires only four external capacitors (0.1µF). The ST232CWR is ideal for use in portable computers, low power modems, interface translation, battery-powered RS-232 systems, and multi-drop RS-232 networks.
