一般说明：SP3074EEN-L/TR
SP3074EEN-L/TR-SP3078E差分线路收发器是适用于平衡的双向通讯多点总线传输线并同时遵守RS-485和RS-422 EIA标准。每个设备包括差分驱动器和差分接收器的示意图。所有装置使用3.3V电源供电。高接收器输入阻抗允许大量的收发器共享公共数据总线，而保持信号余量且无过多负载或使用昂贵的中继器。高阻抗驱动器输出在整个共模上保持不变电压范围为-7至+ 12V。接收者将无法确保输入断开，短路或短路时输出逻辑1终止。驱动器内置短路保护以及热过载关机功能，以防止总线争用或电缆过多的功耗故障。所有RS-485接收器输入和驱动器输出均为ESD保护高达±15kV（气隙和人体）型号）和最高±8kV接触放电（IEC 61000-4-2）。 SP3074EEN-L/TR-SP3078E设备可能无法实现如果连接的接收器，则具有最佳的传输性能包括一个无端到5.0V的偏置网络电阻。请参阅MaxLinear应用说明ANI＃21有关更多详细信息。
