Description

The ST232AB/AC 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 ST232AB/AC

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

networks.
