5v/18v,cmos layout , is it easy to latchup in 18v?
drabos:i want to design digital and analog mixed circuits, i design digital parts in 5v and analog parts in 18v ,should i pay attention to the place that 5v to 18v,and how?
strennor:Is isolation between transistors because of latchup? using guard ring is ok?
i am a beginner,thank you!!!
