Customer use SN74HC125 in their application and face to VOH output voltage level issue.
They connect 3.3V for Vcc power supply, and measure output voltage is only 3.1V even there are no load connection at output side.
I have reference to E2E post below. If there are no load connection, IOH should be close to 0 and less voltage drop at output side.
My question are,
1. Does 3.1V output voltage make sense if Vcc=3.3V?
2. if yes, what may cause output voltage drop if no load connection?
