具有復(fù)位和電壓轉(zhuǎn)換的 4 通道、1.65V 至 5.5V I2C/SMBus 開關(guān)

TCA9546A 是一款通過 I2C 總線控制的四路雙向轉(zhuǎn)換開關(guān)。串行時(shí)鐘/串行數(shù)據(jù) (SCL/SDA) 上行對(duì)分散到四個(gè)下行對(duì)，或者通道。根據(jù)可編程控制寄存器的內(nèi)容，可選擇任一單獨(dú) SCn/SDn 通道或者通道組合。\n\n一個(gè)低電平有效 (RESET) 輸入使得 TCA9546A 能夠在其中一個(gè)下行 I2C 總線長(zhǎng)時(shí)間處于低電平狀態(tài)時(shí)恢復(fù)。將 RESET 下拉為低電平會(huì)使 I2C 狀態(tài)機(jī)復(fù)位，并且使所有通道取消選中，這一功能與內(nèi)部加電復(fù)位功能的作用一樣。\n\n開關(guān)上建有導(dǎo)通柵極，這樣 VCC 端子引腳便可用于限制 TCA9546A 傳遞的最大高壓。這允許在每個(gè)對(duì)上使用不同的總線電壓，以便 ? 4 選 1 雙向轉(zhuǎn)換開關(guān) \n? 與 I2C 總線和 SMBus 兼容\n? 低電平有效復(fù)位輸入\n? 三個(gè)地址引腳，I2C 總線上最多支持八個(gè) TCA9546A 器件\n? 通過 I2C 總線進(jìn)行通道選擇，可任意組合\n? 上電時(shí)所有開關(guān)通道取消選定\n? 低 RON 開關(guān)\n? 支持在 1.8V、2.5V、3.3V 和 5V 總線間進(jìn)行電壓電平轉(zhuǎn)換\n? 上電時(shí)無干擾\n? 支持熱插入\n? 低待機(jī)電流\n? 工作電源電壓范圍為 1.65V 至 5.5V\n? 5.5V 耐壓輸入\n? 0 至 400kHz 時(shí)鐘頻率\n? 閂鎖性能超過 100mA，符合 JESD 78 規(guī)范\n?
