Hello Anbarasu,

Why do you need to calculate the specifications? Are you using the device and it is not behaving according to the datasheet specks?

The fall time specks were measurements gathered through testing. If you trying to measure the fall time yourself. You can use a scope.

Thanks,

Nir

Hello Anbarasu,

Understood, thanks for explaining! As I mentioned earlier my best suggestion is to use a scope.

I personally haven't fully read it, but it seems to have the information you are looking for.

Thanks,

Nir
