Hi team,

We want to check output status when input is floating. Could you please help check it? Thanks.

The output might be high, or low, or switching between them. See [FAQ] How does a slow or floating input affect a CMOS device?

Hey Frank,

This FAQ may help too:.

The answer is straight forward, for a buffer Y = A and if A is unknown then that means Y is unknown.
