Complete, Isolated, 3.3V RS-485/RS-422 Data Interface

General Description The MAX3480A/MAX3480B are electrically isolated RS-485/RS-422 data-communications interfaces. Transceivers, optocouplers, and a transformer are all included in one low-cost, 28-pin DIP package. A single +3.3V supply on the logic side powers both sides of the interface. The MA

完備的、隔離型、3.3V、RS-485/RS-422數(shù)據(jù)接口

MAX3480A/MAX3480B均為電氣隔離的RS-485/RS-422數(shù)據(jù)通信接口。收發(fā)器、光耦合器和變壓器都集成在一個(gè)低成本的28引腳DIP封裝中。接口的兩側(cè)均通過邏輯側(cè)的+3.3V單電源供電。\n\n MAX3480B具有低擺率驅(qū)動(dòng)器，可充分降低EMI并減少因電纜端接不當(dāng)引起的反射，從而實(shí)現(xiàn)數(shù)據(jù)速率高達(dá)250kbps的無誤差數(shù)據(jù)傳輸。MAX3480A的驅(qū)動(dòng)器擺率不受限制，因此傳輸速率高達(dá)2.5Mbps。\n\n 這些器件的典型靜態(tài)電源電流消耗為180mA。MAX3480B提供功耗僅為0.2μA的低功耗關(guān)斷模式。\n\n 驅(qū)動(dòng)器具有短路限流功能，并且通過熱關(guān) ? 隔離式數(shù)據(jù)接口高達(dá) 1600VRMS（1分鐘）\n\n? 限擺率數(shù)據(jù)傳輸(MAX3480B)\n\n? 高速、隔離式2.5Mbps RS-485接口(MAX3480A)\n\n? 相對于隔離地的共模輸入電壓范圍：-7V至+12V\n\n? 3.3V單電源\n\n? 用于驅(qū)動(dòng)器過載保護(hù)的限流和熱關(guān)斷功能\n\n? 標(biāo)準(zhǔn)28引腳DIP封裝;
