18 years agoInterfacing MaxII Micro to 5v TTL
Hello, I got myself a Max Micro kit, and I'm planning to interface this with a 5v TTL device. But I'm not sure if I\O pins are 5v tolerant. What can I do to interface a max micro to 5v TTL devices...

Something like a 74LVT245 http://www.fairchildsemi.com/pf/74/74lvt245.html 3.3V but 5V tolerant. Guess it depends on how many IOs etc you have on your interface and what the fan out is etc Rgds
