Overview
The ST232BTR is a 5V powered multi-channel RS-232 driver and receiver device manufactured by STMicroelectronics. This component is designed to comply with the EIA/TIA-232 and V.28 communication standards, making it suitable for applications where ±12V is not available. The ST232BTR uses a single 5V power supply and requires only four external capacitors (0.1 µF) for operation. It is particularly useful in low-power and portable applications due to its efficient power management and compact design.
