一般說明：MAX489CSD+T
MAX481，MAX483，MAX485，MAX489CSD+T–MAX491和MAX1487是低功耗收發器，用于RS-485和RS422通信。每個部分包含一個驅動程序和一個驅動程序接收器。 MAX483，MAX487，MAX488和MAX489具有降低的擺率驅動器，可最大程度降低EMI和減少因電纜端接不當而引起的反射，從而允許高達250kbps的無錯誤數據傳輸。
MAX481，MAX485，MAX490，MAX491和MAX1487不受限制，允許它們傳輸速率高達2.5Mbps。這些收發器的功耗介于120μA至500μA之間。空載或滿載禁用時的電源電流司機。另外，MAX481，MAX483和MAX487具有消耗電流的低電流關機模式僅0.1μA。所有部件均采用5V單電源供電。驅動器受到短路電流限制并受到保護防止因熱關斷而造成的過多功耗將驅動器輸出置于高阻抗狀態的電路。接收器輸入具有故障安全功能，如果輸入開路，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，允許最高128 MAX487 /總線上的MAX1487收發器。使用MAX489CSD+T–MAX491獲得全雙工通信，而MAX481，MAX483，MAX485，MAX487和MAX1487專為半雙工應用而設計。
