ST202B中文资料5V供电电压多通道RS-232驱动器和接收器，温度范围[-40℃, +85℃]数据手册ST规格书

描述 Description

The ST202B, ST202C is a two-driver, two-receiver device following EIA/TIA-232 and V.28 communication standards. It is particularly suitable for applications where ± 12 V is not available. The ST202B, ST202C uses a single 5 V power supply and only four external capacitors (0.1 µF). Typical applications are in: portable computers, low power modems, interface translation, and battery-powered RS-232 networks.
