I am doing worst case calculation with PCA9534 minimum high level O/P voltage (@10mA, Vcc=3.3Vsupply) .
As per the datasheet section 7.5, i plotted different voltage levels vs Vcc and approximated a minimum VOH of 2.8V (for 3.3V supply i.e Vcc-VOH=0.5V) .
But looking at the figure 7-17, even for the complete temperature range the difference (Vcc- VOH) < 200mV for ~3.3V.
What shall i consider as the worst case VOH for 3V3 supply with 10mA load?
