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 ST232A 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

Networks.
