This is a elementary question but confusing one.
According to Figure 21(I attached below) in the ADCMP354 datasheet(Rev B), I think at fist comparator connect to n-FET and its drain connect to the output-pin, then if the output of comparator is low, the output of ADCMP354 is high.
However ADCMP354 is active high and non-inverting comparator and if the input is lower than 0.6, the output should be low.
I think Figure 21 is not exactly but I'd like to confirm the truth table of ADCMP354 and ADCMP350.
Is it correct?
Thanks for pointing this out. I think there is an error on the diagram. You have the correct truth table which is the output goes to high impedance if the input is above 0.6 V and will have 0 V output if the input is below 0.6 V. I will notify the product owner of this part to make a necessary action regarding this.
Thanks and best regards,
