一般說明：MAX489ESD+T
MAX481，MAX483，MAX485，MAX489ESD+T-MAX491和MAX1487是用于RS-485和RS422的低功耗收發器通訊。每個部分包含一個驅動程序和一個接收器。 MAX483，MAX487，MAX488和MAX489ESD+T降低擺率驅動器，降低EMI和EMI減少由不正確端接的電纜引起的反射，從而允許高達250kbps的無差錯數據傳輸。驅動器的轉換速率為MAX481，MAX485，MAX490，MAX491和MAX1487不受限制，允許它們傳輸速率高達2.5Mbps。這些收發器的電流介于120μA和500μA之間卸載或滿載禁用時供電電流驅動程序。此外，MAX481，MAX483和MAX487具有消耗的低電流關斷模式僅0.1μA。所有器件均采用5V單電源供電。驅動器的短路電流受限且受到保護
通過熱關斷防止功耗過大將驅動器輸出置于高阻態的電路州。接收器輸入具有故障安全功能如果輸入是開路的，則保證邏輯高輸出。
MAX487和MAX1487具有四分之一單位負載接收器輸入阻抗，允許高達128 MAX487 /MAX1487總線上的收發器。全雙工通信使用MAX489ESD+T-MAX491即可獲得MAX481，MAX483，MAX485，MAX487和MAX1487專為半雙工應用而設計。
