数据: 70-V Fault-Protected RS-485 Transceivers with Cable Invert 数据表
这些设备可以承受过压故障,例如直接短路到电源,接线错误,连接器故障,电缆压坏和工具误应用。它们对ESD事件也很强大,对人体模型规格具有高度保护。
这些器件结合了差分驱动器和差分接收器,可通过单个电源供电。驱动器差分输出和接收器差分输入在内部连接,适用于适用于半双工(双线总线)通信的总线端口。电缆反相引脚(INV)允许主动校正安装期间可能发生的错误导线。在检测到通信错误时,用户可以向INV引脚施加逻辑高电平,有效地反转差分总线端口的极性,从而校正反向总线。
这些器件具有宽共模电压范围,使其适用于长电缆的多点应用。这些器件的特性为-40°C至105°C。
对于3.3 V电源工作的类似功能,请参见SN65HVD1781(SLLS877)。
