Input D is shown as schmidt in fig 2. I have slow input rise time input signal and ouput freq is not same as input.
What is the max rise time allowed on this input?
The recommended maximum input rise time is 1 ms. Can you provide an oscilloscope plot showing the input and output signals you're observing?
Thanks Dave, that explains it. I assumed it being schmidt, any rise time would be tolerated.
I am filering a low freq square wave to get rid of noise so I'll try raing cutoo freq
