[plug] [Off-topic] CMOS 3V3 to TTL 5v buffer

[Euan de Kock]

If your only running it in one direction, eg as an output, then the easiest is through a 74LS01 twice - the 7401 is a logic inverter, and can work at a much higher frequency than 19200. The logic levels on most 74 devices are such that 3.3v is more than enough to register as true logic.
