可熱插拔雙線總線緩沖器

TCA4311A 是一款可熱插拔型 I2C 總線緩沖器，支持在帶電背板上進(jìn)行 I/O 板卡的插拔操作，而不會損壞數(shù)據(jù)和時鐘總線。 控制電路可防止背板與板卡相連接（直到背板上出現(xiàn)停止命令或總線空閑為止），而不會在板卡上發(fā)生總線爭用的情況。 當(dāng)建立連接時，該器件可提供雙向緩沖，從而使背板及板卡電容保持隔離。 在板卡插入過程中，SDA 及 SCL 線路被預(yù)充電至 1V，以最大限度地減小對芯片的寄生電容進(jìn)行充電所需的電流。\n 當(dāng) I2C 總線空閑時，可通過將 EN 引腳設(shè)定為低電平來把 TCA4311A 置于停機(jī)模式之中。 當(dāng) EN 引腳為高電平時，TCA4311 將恢復(fù)正常運(yùn)作。 該器件還包括一個 ? 2.7V 至 5.5V 工作電源電壓范圍 \n? SDA 和 SCL 線路經(jīng)過緩沖，因而增加了扇出\n? SDA 和 SCL 輸入線路與輸出隔離\n? 抗噪聲性能有所改善\n? 低 ICC 芯片停用模式：2C 引腳\n? 閂鎖性能超出 JESD 78 II 類規(guī)范要求的 100mA\n? 200V 機(jī)器模型 (A115-A)\n? 1000V 充電器件模型 (C101);
