一般說明：MAX487EESA+T
MAX481E，MAX483E，MAX485E，MAX487EESA+T-MAX491E和MAX1487E是低功耗收發(fā)器在惡劣環(huán)境中進(jìn)行RS-485和RS-422通信。每個(gè)驅(qū)動(dòng)器輸出和接收器輸入都受到保護(hù)對(duì)抗±15kV靜電放電（ESD）沖擊，沒有閉鎖。這些部件包含一個(gè)驅(qū)動(dòng)器和一個(gè)接收器。 MAX483E，MAX487EESA+T，MAX488E和
MAX489E具有降低擺率的驅(qū)動(dòng)器，可最大限度地降低功耗EMI并減少因不正確終止而引起的反射電纜，從而允許無差錯(cuò)的數(shù)據(jù)傳輸高達(dá)250kbps。 MAX481E的驅(qū)動(dòng)器轉(zhuǎn)換速率，MAX485E，MAX490E，MAX491E和MAX1487E不是有限，允許它們傳輸高達(dá)2.5Mbps。
這些收發(fā)器的電源電流僅為120μA卸載時(shí)或完全加載禁用時(shí)驅(qū)動(dòng)程序（請(qǐng)參閱選擇指南）。另外，MAX481E，MAX483E和MAX487EESA+T具有低電流關(guān)斷功能它們僅消耗0.5μA的模式。所有部件均可運(yùn)行從單+ 5V電源。驅(qū)動(dòng)器的短路電流受限，并受到保護(hù)通過熱關(guān)斷防止功耗過大將輸出置于高阻態(tài)的電路
州。接收器輸入具有保證的故障安全功能如果輸入是開路的，則為邏輯高電平輸出。MAX487E和MAX1487E具有四分之一單位負(fù)載接收器輸入阻抗，最多允許128個(gè)收發(fā)器在公交車上。 MAX488E-MAX491E是專為全雙工通信而設(shè)計(jì)MAX481E，MAX483E，MAX485E，MAX487EESA+T和MAX1487E專為半雙工應(yīng)用而設(shè)計(jì)。對(duì)于非ESD敏感的應(yīng)用，請(qǐng)參見pinand功能兼容MAX481，MAX483，MAX485，MAX487EESA+T-MAX491和MAX1487。
