Overview
The ST232CD, produced by STMicroelectronics, is a 2 driver, 2 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 a compact and efficient solution. The ST232CD is compatible with MAX232 and MAX202, enhancing its versatility in various communication systems.
