Description
.
The ST202 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 ST202 uses a
single 5V power supply and only four external
capacitors (0.1µF). Typical application are in:
Portable Computers, Low Power Modems,
Interfaces Translation, Battery Powered RS-232
Networks.
