Hello, I have a circuit that i will be running the IO lines a reasonable distance, and i would like to amplify the lines from the current 3.3Volt to 5.0volt. I'm sure this is probably a simple task and (hopefully) their is a single IC someone could direct me to. I thought that maybe a Darlington transistor array could work, but I would like to verify this and know the pros and cons. Obviously latency is an issue. Any help is greatly appreciated. Josh.
