Description
The ST232 is a 2 driver, 2 receiver device
following EIA/TIA-232 and V.28 communication
standard. It is particularly suitable for applications
where ±12 V is not available. The ST232 uses a
single 5 V power supply and only four external
capacitors (0.1 µF). Typical applications are in:
portable computers, low power modems,
interfaces translation, battery powered RS-232
system, multi-drop RS-232 networks.
