Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A standard TTL logic gate has an output current sourcing specification of 400µA and sinking of 16mA. Calculate the fan-out for both HIGH and LOW states and determine the operational fan-out.

💡 Hint: Use the known output and input current specifications.

Challenge 2 Hard

You have a NAND gate that can source 2mA and sink 10mA. Each logic gate input requires 500µA. How many inputs can it drive?

💡 Hint: Calculate for both HIGH and LOW, then choose the lesser value.
