3.3V供电，热插拔，极性自动翻转的半双工RS-485收发器

UM3487E系列是一款具有3.3V供电、±15kV ESD保护、失效保护、热插拔、自动极性反转功能的RS-485收发器。这些器件具有失效保护电路，可在接收器输入开路、短路或闲置时确保接收器输出为逻辑高电平。这意味着如果端接总线上的所有发射器都被禁用（高阻抗），接收器输出将为逻辑高电平。UM3487E具有低摆率驱动器，可降低EMI并减少因电缆端接不当引起的反射，从而实现高达500kbps的无误差数据传输。所有发射器输出和接收器输入均能够耐受±8kV的人体放电模型和±15kV的IEC61000-4-2标准的空气间隙放电。\nUM3487E具备电缆自动反转功能，可在电缆连接错误时反转RS485总线 - 自动极性反转 RS-485收发器\n- I/O逻辑电平与 5V、3.3V 和 1.8V 逻辑电平兼容\n- RS-485 I/O引脚提供ESD保护\n-- ±15kV—IEC61000-4-2, 空气间隙放电\n-- ±8kV—IEC61000-4-2, 接触放电\n- 真正的失效保护接收器\n- 增强型压摆率限制\n- 共模输入电压范围：-7V 至 +12V\n- 支持总线连接多达256个节点\n- 热关断\n- 驱动过载限流保护;
