一般說明：MAX489EESD+T
MAX481E、MAX483E、MAX485E、MAX489EESD+T–MAX491E 和 MAX1487E 是低功耗收發(fā)器，用于惡劣環(huán)境下的 RS-485 和 RS-422 通信。每個驅(qū)動器輸出和接收器輸入都受到保護(hù)抗 ±15kV 靜電放電 (ESD) 沖擊，沒有閂鎖。這些部件包含一個驅(qū)動器和一個接收者。 MAX483E、MAX487E、MAX488E 和MAX489EESD+T具有降低壓擺率的驅(qū)動器，可最大限度地減少EMI 并減少不正確端接電纜引起的反射，從而實(shí)現(xiàn)無差錯的數(shù)據(jù)傳輸高達(dá) 250kbps。 MAX481E 的驅(qū)動器壓擺率，MAX485E、MAX490E、MAX491E 和 MAX1487E 不是限制，允許它們傳輸高達(dá) 2.5Mbps。這些收發(fā)器在空載或滿載且禁用時消耗低至 120μA 的電源電流驅(qū)動程序（請參閱選擇指南）。此外，MAX481E、MAX483E 和 MAX487E 具有低電流關(guān)斷功能在這種模式下，它們僅消耗 0.5μA。所有部件均采用 +5V 單電源供電。驅(qū)動器受短路電流限制，并受到保護(hù)防止熱關(guān)斷造成的過度功耗將其輸出置于高阻抗的電路狀態(tài)。接收器輸入具有故障安全功能，可在輸入開路時保證邏輯高輸出。
MAX487E 和 MAX1487E 具有四分之一單位負(fù)載接收器輸入阻抗，允許總線上多達(dá) 128 個收發(fā)器。 MAX488E–MAX491E 是
專為全雙工通信而設(shè)計，而MAX481E、MAX483E、MAX485E、MAX487E 和MAX1487E 設(shè)計用于半雙工應(yīng)用。
對于對 ESD 不敏感的應(yīng)用，請參見引腳和功能兼容的 MAX481、MAX483、MAX485、MAX489EESD+T–MAX491 和 MAX1487。
