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 ± 12 V is not available. The ST202 uses a single 5 V power supply and only four external capacitors (0.1 µF). Typical application are in: portable computers, low power modems, interfaces translation, battery powered RS-232 networks.
