MAX230 的相关技术信息

概述

MAX220-MAX249系列线驱动器/接收器，专为EIA/TIA-232E以及V.28/V.24通信接口设计，尤其是无法提供±12V电源的应用。

这些器件特别适合电池供电系统，这是由于其低功耗关断模式可以将功耗减小到5µW以内。MAX225、MAXX233、MAX235以及MAX245/MAX246/MAX247不需要外部元件，推荐用于印刷电路板面积有限的应用。

关键特性 应用

对于低电压、集成ESD应用： MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E: +3.0V至+5.5V、低功耗、最高1Mbps、真正的RS-232收发器，使用4个0.1µF外部电容(MAX3246E提供UCSP™封装)
对于低成本应用： MAX221E: ±15kV ESD保护、+5V、1µA、单路RS-232收发器，带AutoShutdown™
