+5 V低功耗EIA RS-485收發(fā)器

ADM485是一款差分線路收發(fā)器，適用于多點(diǎn)總線傳輸線路的高速雙向數(shù)據(jù)通信。它針對(duì)平衡數(shù)據(jù)傳輸而設(shè)計(jì)，符合EIA標(biāo)準(zhǔn)RS-485和RS-422。該器件內(nèi)置一個(gè)差分線路驅(qū)動(dòng)器和一個(gè)差分線路接收器，驅(qū)動(dòng)器和接收器均可獨(dú)立使能。禁用時(shí)，輸出處于三態(tài)。 ADM485采用+5 V單電源供電。熱關(guān)斷電路可防止總線競(jìng)爭(zhēng)或輸出短路導(dǎo)致功耗過(guò)大。故障條件下，如果檢測(cè)到內(nèi)部驅(qū)動(dòng)器電路的溫度顯著升高，此特性將強(qiáng)制驅(qū)動(dòng)器輸出進(jìn)入高阻抗?fàn)顟B(tài)。\n\n 一條總線上最多可以同時(shí)連接32個(gè)收發(fā)器，但任一時(shí)間只能使能一個(gè)驅(qū)動(dòng)器。因此，其余禁用的驅(qū)動(dòng)器不能向總線提供負(fù)載。為此，ADM485驅(qū)動(dòng)器在禁用和關(guān)斷時(shí) ? 符合EIA RS-485標(biāo)準(zhǔn)\n\n? 數(shù)據(jù)速率：5 Mbps\n\n? 5 V單電源\n\n? 總線共模范圍：–7 V至+12 V\n\n? 高速、低功耗BiCMOS工藝;
