Overview
The ST232BD, produced by STMicroelectronics, is a 5V powered multi-channel RS-232 driver and receiver IC. This device is designed to comply with the EIA/TIA-232 and V.28 communication standards, making it suitable for various applications where ±12V power supply is not available. The ST232BD uses a single 5V power supply and requires only four external capacitors (0.1µF) for operation. It is particularly useful in scenarios where low power consumption and compact design are essential.
