带有中断逻辑和复位的二选一I²C总线主选择器

PCA9541是一款二选一 I²C总线主器件选择器，主要用于高可靠性双主器件I²C总线应用，此类应用中即使一个主器件发生故障或拔出控制器卡进行维护，仍需要进行系统操作。两个主器件（例如，主要和备用）分别位于通往相同下游I²C总线从器件的不同I²C总线上。I²C总线命令可通过任一I²C总线主器件发送，每次使用命令时需选择一个主器件。任何时候，任一主器件均可在另一主器件被禁用或从系统拔出时获得对从器件的控制。发生故障的主器件会从系统隔离且不会影响在线主器件和下游I²C总线上从器件之间的通信。\n提供不同构架的两个版本。PCA9541/01在启动时选择通道0而PCA9541/03在启动后不选择任何通 二选一双向主选择器\nI²C总线接口逻辑；兼容SMBus标准\nPCA9541/01上电时选择通道0\nPCA9541/03上电时不选择任何通道且任一主器件均可控制总线\n低电平有效的中断输入\n2个低电平有效的中断输出\n低电平有效的复位输入\n4个地址引脚允许I²C总线上最多有16个器件\n通过I²C总线进行通道选择\n总线初始化/恢复功能\n总线通信量传感器\n低Ron开关\n允许1.8 V、2.5 V、3.3 V和5 V总线之间的电压电平变换\n上电时没有脉冲干扰\n支持热插入\n两个主器件的软件完全相同\n低待机电流\n2.3 V至5.5 V的工作电源电压范围\n6.0 V耐受输入\;
