3.3 V、全雙工、低功耗收發(fā)器; ? 采用3.3 V電源供電\n\n? 與5 V邏輯兼容\n\n? 在整個共模范圍內(nèi)符合EIA RS-485/RS-422標(biāo)準(zhǔn)\n\n? 數(shù)據(jù)速率選項(xiàng)：10 Mbps\n\n? 半雙工和全雙工選項(xiàng);

ADM3483/ADM3485/ADM3488/ADM3490/ADM3491均為低功耗、差分線路收發(fā)器，采用3.3 V單電源供電。這些器件具有低功耗特性和關(guān)斷模式，非常適合對功耗敏感的應(yīng)用。\n\n ADM3488/ADM3490/ADM3491適用于全雙工通信，而ADM3483/ADM3485則適用于半雙工通信。\n\n????????????????????? ADM3485/ADM3490/ADM3491的傳輸速率最高可達(dá)10 Mbps。接收器輸入阻抗為12 kΩ，總線上最多可以連接32個收發(fā)器。熱關(guān)斷電路可防止總線競爭或輸出短路導(dǎo)致功耗過大。故障條件下，如果檢測到內(nèi)部驅(qū)動器電路的溫度顯著升高，熱關(guān)斷電路將強(qiáng)制驅(qū)動器輸出進(jìn)入高阻抗?fàn)顟B(tài)。如果輸入未連接（浮地），接收器所具有的故障安全特性將使輸出保持邏輯高狀態(tài)。這些器件的額定溫度范圍是商用和工業(yè)溫度范圍。\n\n???????????????????? ADM3483/ADM3485/ADM3488/ADM3490提供8引腳SOIC_N封裝，ADM3491則提供14引腳SOIC_N封裝。\n\n
