Overview
The ST232BN, 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 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 and compact. The ST232BN is compatible with MAX232 and MAX202, and it is ideal for use in various low-power and portable applications.
