Challenge Problems
Push your limits with challenges.
Question 1
Design a circuit with an open drain output and explain how the pull-up resistor affects the signal integrity.
💡 Hint: Consider what would happen if you removed the pull-up.
Question 2
If two open drain outputs are connected to a shared line, what will happen if both attempt to drive the output low? Illustrate your answer with a diagram.
💡 Hint: Visualize the effect of both MOSFETs acting together.
