I came up with this circuit. Is it good or bad to use diodes? In my opinion, this is better than a divider or a FET, at least faster, as you can see from the waveforms. Will such a circuit create bounce and noise? My oscilloscope has a bandwidth of 50 MHz and does not accurately measure voltage.
I also tried using a 2.4 V Zener diode, but it has a large capacitance so I got bursts below GND and above 3.3 V.
