I'm dealing with clock buffer and trying to determine how output levels depends on the input. I'm using information from the datasheet. Here is the table with information:
I don't understand the information in this table completely. We see that output high voltage is measured at the certain conditions. The supply voltage is VDD=Min=1.65. The input voltage is VIH or VIL. I don't understand that. I expect the output voltage to be measured at the certain input voltage.
