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 ±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.
