数据: SN65HVD17xx Fault-Protected RS-485 Transceivers With Extended Common-Mode Range 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。在?? HVD1785,?? HVD1786和?? HVD1787中,驱动器差分输出和接收器差分输入在内部连接,形成适合半双工(双线总线)通信的总线端口。在'HVD1793中,驱动器差分输出和接收器差分输入是独立的引脚,以形成适用于全双工(四线总线)通信的总线端口。这些端口具有较宽的共模电压范围,使该器件适用于长距离电缆的多点应用。这些器件的特性为?40°C至105°C。
对于具有3.3 V电源工作的类似功能,请参见SN65HVD1781(SLLS877)。
