ADM560

超低功耗、低電平有效關(guān)斷和高電平有效接收器使能; ? RS-232 兼容\n\n? 以3 V或5 V邏輯工作\n\n? 超低功耗CMOS: 1.3 mA（工作時(shí)）\n\n? 低功耗關(guān)斷模式：0.2 μA;

ADM560/ADM561均為接口器件，內(nèi)置4個(gè)驅(qū)動(dòng)器和5個(gè)接收器，采用+3.3 V單電源供電，符合EIA-232標(biāo)準(zhǔn)。這些器件具有片上DC-DC轉(zhuǎn)換器，無(wú)需±5 V雙電源。此DC-DC轉(zhuǎn)換器內(nèi)置倍壓器和電壓反相器，可在內(nèi)部從+3.3 V輸入電源產(chǎn)生±6.6 V電壓。\n\n?????ADM560和ADM561的功耗僅為5 mW，非常適合電池供電應(yīng)用及其它對(duì)功耗敏感的應(yīng)用。同時(shí)提供關(guān)斷功能，可將功耗降至0.66 μW。\n\n?????ADM560具有低電平有效關(guān)斷信號(hào)和高電平有效接收器使能信號(hào)。關(guān)斷模式下，仍有兩個(gè)接收器保持活動(dòng)狀態(tài)，以便監(jiān)控外設(shè)。利用此特性，器件可以在外設(shè)開(kāi)始通信之前始終保持關(guān)斷狀態(tài)?；顒?dòng)接收器可以提醒處理器，然后通過(guò)處理器讓ADM560脫離關(guān)斷模式。\n\n?????ADM561具有高電平有效關(guān)斷信號(hào)和低電平有效接收器使能信號(hào)。關(guān)斷模式下，該器件的所有接收器均禁用。\n\n?????ADM560/ADM561采用CMOS技術(shù)制造，功耗極低，并具有高度可靠的過(guò)壓保護(hù)和防閂鎖特性。接收器輸入可以承受最高±25 V的電壓。發(fā)射器輸入可以采用3V或5V邏輯電平驅(qū)動(dòng)。因此，這些器件可以在3 V/5 V混合電源系統(tǒng)中工作。\n\n?????ADM560/ADM561提供28引腳SO和28引腳SSOP兩種封裝。
