ADM4855

全雙工RS-485/RS-22收發(fā)器，提供500kbps數(shù)據(jù)速率; ? 符合EIA RS-485/RS-422標(biāo)準(zhǔn)\n\n? 壓擺率降低以實現(xiàn)低電磁輻射(EMI)\n\n? 真故障安全接收器輸入\n\n? 關(guān)斷模式電源電流：2 μA（最大值）\n\n? 一條總線上最多連接256個收發(fā)器;

ADM4850-ADM4857均為差分線路收發(fā)器，適用于多點總線傳輸線路的高速全雙工和半雙工數(shù)據(jù)通信。這些器件針對平衡數(shù)據(jù)傳輸而設(shè)計，符合EIA標(biāo)準(zhǔn)RS-485和RS-422。ADM4850-ADM4853均為半雙工收發(fā)器，驅(qū)動器和接收器共用差分線路，但各自具有獨立的使能輸入。ADM4854-ADM4857均為全雙工收發(fā)器，驅(qū)動器輸出和接收器輸入各具有專用差分線路。\n\n?????????? 這些器件具有1/8單位負(fù)載接收器輸入阻抗，允許一條總線最多連接256個收發(fā)器。由于任一時間僅使能一個驅(qū)動器，因此禁用或關(guān)斷驅(qū)動器的輸出處于三態(tài)，避免總線過載。????????? 接收器輸入具有真故障安全特性，當(dāng)輸入開路或短路時，可確保輸出保持邏輯高電平。這樣，通信開始之前及結(jié)束時，可保證接收器輸出處于已知狀態(tài)。\n\n?????????? 為了減小端接不當(dāng)總線的反射所引起的電磁輻射(EMI)和數(shù)據(jù)誤差，驅(qū)動器輸出壓擺率受限。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。\n\n?? 這些器件的額定溫度范圍為商用和工業(yè)溫度范圍，提供8引腳SOIC和LFCSP封裝。
