实际电路中出现该波形,红色为输出波形,黑色为select波形,,在select为低电压时,开关切到S1,理应输出0V,但输出并未为0V,输出类型于S2,原因是什么?

您好, 感觉您的串扰来自与电源,请检查并重新规划VDD退耦电容摆放位置和电容位置, 电容容值0.1 μF~ 10 μF, 耐压值不要超过10V, 以免电容降容影响效果。详情参见11.2 Layout Example https://www.ti.com.cn/cn/lit/ds/symlink/tmux1237.pdf#page=24
您好,
输入信号只能是0~Vdd, 如果超过这个数值,未超过Absolute Maximum Ratings中的-0.5V, 只能保证不坏,不能保证功能正常。
