ST232BTR

ST232BTR is a 5V-powered multi-channel RS-232 driver and receiver. It is particularly suitable for applications where ±12V is not available. It uses a single 5V power supply and only four external capacitors (0.1µF). It is used in applications such as portable computers, low-power modems, interface translation, battery-powered RS-232 systems, multi-drop RS-232 networks.
