My daq outputs 3.3V, and even though the device I'm driving says its TTL compatibile, apparently its not enough and I need 5V. What solutions are there? I'm completely new to all of this.
You can use something like a SN74LVCC4245A to convert the voltage to a 5V signal. You will need a 3.3V and a 5V power supply to power the chip.
