HD3SS460: How to measure Mux is open or not

Hello,

Here is a question I want to hear your opinions.

For my understanding, MUX is a switch, if one path is switch on, I can use multimeter measure the resistance between in and out, it should be very low impedance. But if this MUX path is switch off, it should be very high impedance, so can I use this method to check if this path is on or off?

Also, if I inject a signal at  IN, then I use oscilloscope to check OUT, if this path is ON, I expect I can see the same signal. Can I use this method to check if the path is on or off?

Looking forward to your reply.

Thanks.
