简单型双线总线缓冲器

PCA9525是一款用于应用中总线缓冲的CMOS单片集成电路，包括I²C总线、SMBus、DDC、PMBus和基于相似原理的其他系统。\n该缓冲器可扩展总线负载限制，方法是缓冲SCL和SDA线路，从而使缓冲器两侧实现可允许的最大总线电容。\nPCA9525包括一个用于时钟信号的单向缓冲器和一个用于数据信号的双向缓冲器。因此，不支持用于部署时钟延伸的从机器件。\n在其最基本的应用中，缓冲器允许将延伸的从器件连接至一个（或多个）主器件。在此情况下，所有主器件均置于PCA9525的Sxx_IN侧。\n方向针脚(DIR)进一步增强了此功能，因为它允许保留单向时钟信号，从而允许主器件位于缓冲器的两侧。\ 简单阻抗隔离缓冲器，适合于双线总线\n4 mA最大静态开漏下拉功能，支持宽范围的总线标准\n使用I²C总线（标准模式、快速模式）、SMBus（标准和高功耗模式）和PMBus\n快速切换时间允许在超过1 MHz频率的条件下操作\n启用允许将总线段码断开\n输入迟滞提供抗噪性\n工作电压范围：2.7 V至5.5 V\n极低电源电流\n满足大多数常用双线总线应用的快速安装需要;
