帶有中斷邏輯和復(fù)位的二選一I2C總線主選擇器

PCA9541是一款二選一 I2C總線主器件選擇器，主要用于高可靠性雙主器件I2C總線應(yīng)用，此類應(yīng)用中即使一個主器件發(fā)生故障或拔出控制器卡進行維護，仍需要進行系統(tǒng)操作。兩個主器件（例如，主要和備用）分別位于通往相同下游I2C總線從器件的不同I2C總線上。I2C總線命令可通過任一I2C總線主器件發(fā)送，每次使用命令時需選擇一個主器件。任何時候，任一主器件均可在另一主器件被禁用或從系統(tǒng)拔出時獲得對從器件的控制。發(fā)生故障的主器件會從系統(tǒng)隔離且不會影響在線主器件和下游I2C總線上從器件之間的通信。\n提供不同構(gòu)架的兩個版本。PCA9541/01在啟動時選擇通道0而PCA9541/03在啟動后不選擇任何通 二選一雙向主選擇器\nI2C總線接口邏輯；兼容SMBus標(biāo)準(zhǔn)\nPCA9541/01上電時選擇通道0\nPCA9541/03上電時不選擇任何通道且任一主器件均可控制總線\n低電平有效的中斷輸入\n2個低電平有效的中斷輸出\n低電平有效的復(fù)位輸入\n4個地址引腳允許I2C總線上最多有16個器件\n通過I2C總線進行通道選擇\n總線初始化/恢復(fù)功能\n總線通信量傳感器\n低Ron開關(guān)\n允許1.8 V、2.5 V、3.3 V和5 V總線之間的電壓電平變換\n上電時沒有脈沖干擾\n支持熱插入\n兩個主器件的軟件完全相同\n低待機電流\n2.3 V至5.5 V的工作電源電壓范圍\n6.0 V耐受輸入\;
