ST202CWR

5V供电多通道RS - 232驱动器和接收器 5V Powered multi-channel RS-232 drivers and receivers

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.
