Challenge Problems
Push your limits with advanced challenges
If you have a TTL output capable of 16mA and you're driving seven inputs each drawing 40µA, will this exceed the fan-out limitations?
💡 Hint: Convert everything to the same units and add them up!
Calculate the worst-case noise scenario where the input voltage is 3V under noise margin. How would it affect your TTL reliability?
💡 Hint: Consider the voltage levels and how noise may push them into incorrect logic!
