CD4024芯片工作电压为5V时，时钟输入频率最大为多少MHZ？

In the table below the RECOMMENDED OPERATING CONDITIONS in the CD4024 chip specification, when the chip is operating at 5V, the maximum input pulse frequency is 3.5MHZ; In the table below DYNAMIC ELECTRICAL CHARACTERISTICS, when operating at 5V, the maximum pulse input range is 3.5-7MHZ; What is the difference between these two, and which of the actual working maximum frequency should prevail?

Alice：

您好，

       “RECOMMENDED OPERATING CONDITIONS” 中参数是芯片承诺稳定工作的情况，请工作在此条件下。
