3.3V供電，熱插拔，極性自動翻轉(zhuǎn)的半雙工RS-485收發(fā)器

UM3487E系列是一款具有3.3V供電、±15kV ESD保護、失效保護、熱插拔、自動極性反轉(zhuǎn)功能的RS-485收發(fā)器。這些器件具有失效保護電路，可在接收器輸入開路、短路或閑置時確保接收器輸出為邏輯高電平。這意味著如果端接總線上的所有發(fā)射器都被禁用（高阻抗），接收器輸出將為邏輯高電平。UM3487E具有低擺率驅(qū)動器，可降低EMI并減少因電纜端接不當引起的反射，從而實現(xiàn)高達500kbps的無誤差數(shù)據(jù)傳輸。所有發(fā)射器輸出和接收器輸入均能夠耐受±8kV的人體放電模型和±15kV的IEC61000-4-2標準的空氣間隙放電。\nUM3487E具備電纜自動反轉(zhuǎn)功能，可在電纜連接錯誤時反轉(zhuǎn)RS485總線 - 自動極性反轉(zhuǎn) RS-485收發(fā)器\n- I/O邏輯電平與 5V、3.3V 和 1.8V 邏輯電平兼容\n- RS-485 I/O引腳提供ESD保護\n-- ±15kV—IEC61000-4-2, 空氣間隙放電\n-- ±8kV—IEC61000-4-2, 接觸放電\n- 真正的失效保護接收器\n- 增強型壓擺率限制\n- 共模輸入電壓范圍：-7V 至 +12V\n- 支持總線連接多達256個節(jié)點\n- 熱關斷\n- 驅(qū)動過載限流保護;
