Challenge Problems
Push your limits with challenges.
Question 1
You have a CPU output that can support up to 20mA, and you want to drive 5 devices that need 7mA each. Will you need a buffer? If yes, calculate the maximum number of devices it can directly drive.
💡 Hint: Calculate the total current needed and compare it to the output.
Question 2
Design a simple circuit illustration showing the use of buffers with TTL outputs, indicating how you would connect multiple devices to a single output pin.
💡 Hint: Draw one input leading to multiple outputs, labeling each connection.
