ADM307xE均為3.3 V低功耗數(shù)據(jù)收發(fā)器，提供±15 kV ESD保護(hù)，適用于多點(diǎn)總線(xiàn)傳輸線(xiàn)路的全雙工和半雙工通信。這些器件針對(duì)平衡數(shù)據(jù)傳輸而設(shè)計(jì)，符合TIA/EIA標(biāo)準(zhǔn)RS-485和RS-422。
                         

此外還具有?單位負(fù)載接收器輸入阻抗，允許一條總線(xiàn)最多連接256個(gè)收發(fā)器。由于任一時(shí)間僅使能一個(gè)驅(qū)動(dòng)器，因此禁用或關(guān)斷驅(qū)動(dòng)器的輸出處于三態(tài)，避免總線(xiàn)過(guò)載。

接收器輸入具有真故障安全特性，無(wú)需外部偏置電阻；當(dāng)輸入開(kāi)路或短路時(shí)，可確保提供邏輯高輸出電平。這樣，通信開(kāi)始之前及結(jié)束時(shí)，可保證接收器輸出處于已知狀態(tài)。
