Description

The ST232A is a 2 driver, 2 receiver device following EIA/TIA-232 and V.28 communication standard. It is particularly suitable for applications where ±12V is not available. The ST232 uses a
single 5V power supply and only four external capacitors (0.1µF). Typical applications are in:Portable Computers, Low Power Modems,Interfaces Translation, Battery Powered RS-232 System,Multi-Drop RS-232 Networks.
