Looking for a MicroController Recommedation

Depending on what you're driving with them, this "conversion" may be a no-op. AIUI 3.3V outputs normally swing rail-to-rail, and 3.3V is well above the TTL "high" input threshold, so you can just feed a 3.3V output directly to a TTL input, provided they share GND. While I daresay there are exceptions (I know of none, but I'd be surprised if there weren't), I imagine most 5V logic families stay reasonably close to TTL's input thresholds and thus work equally well with null conversion here. I'm sure someone will correct me if this guess is wrong.... Perhaps I've just misunderstood something, but I would expect to find this on its datasheet. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
