Me: https://wodewangzhishime.blogspot.com/2023/12/sequential-94-cross.html . .This article mention that if you put too many inverters, the circuit delay too much. . Consequently, stack overflow occur. . Today, we give one more example in which the cirucit doesn't put too many inverters, however, stack overflow sitll occur.

.

I'm gonna input 3-2-1-4.  

3-2 comply with the combination of NPN-PNP.

.

Look at the above picture. . There're 2 inverters only. . However, 3-2 both comply with the combination of NPN-PNP. . Consequently, stack overflow occur.

.

John: Because, 3-2 are closed to each other. . The frequency is too high.

Me: In this case, stack overflow occur.
