ADM4851

5 V、⅛负载、限摆率、RS-485/RS-422收发器（半双工、500 KBPS）; • 符合电子工业联盟(EIA)RS-485/RS-422标准 \n\n• 数据速率： 500 kbps \n\n• 半双工和全双工选项\n\n• 压摆率降低以实现低电磁辐射(EMI) \n\n• 真故障保护接收器输入\n\n• 关断模式电源电流：5 µA（最大值）\n\n• 一条总线上最多连接256个收发器\n\n• 禁用或关断时输出处于高阻抗状态\n\n• 总线共模范围：−7 V至+12 V \n\n• 热关断和短路保护\n\n• 与MAX308x引脚兼容 \n\n• 额定温度范围：-40℃至+85°C\n\n• 提供8引脚SOIC、8引脚LFCSP和8引脚MSOP封装\n\n• 通过汽车应用认证;

ADM4850-ADM4857均为差分线路收发器，适用于多点总线传输线路的高速全双工和半双工数据通信。这些器件针对平衡数据传输而设计，符合EIA标准RS-485和RS-422。ADM4850-ADM4853均为半双工收发器，驱动器和接收器共用差分线路，但各自具有独立的使能输入。ADM4854-ADM4857均为全双工收发器，驱动器输出和接收器输入各具有专用差分线路。\n\n 这些器件具有1/8单位负载接收器输入阻抗，允许一条总线最多连接256个收发器。由于任一时间仅使能一个驱动器，因此禁用或关断驱动器的输出处于三态，避免总线过载。 接收器输入具有真故障安全特性，当输入开路或短路时，可确保输出保持逻辑高电平。这样，通信开始之前及结束时，可保证接收器输出处于已知状态。\n\n 为了减小端接不当总线的反射所引起的电磁辐射(EMI)和数据误差，驱动器输出压摆率受限。热关断电路可防止总线竞争或输出短路导致功耗过大。\n\n   这些器件的额定温度范围为商用和工业温度范围，提供8引脚SOIC、LFCSP (ADM4850/ADM4851/ADM4852/ADM4853)和MSOP（仅ADM4850）封装。\n\n
