I have a 12v powered 16-channel relay board, that required 5v logic level signals to control the relays. However, I am using a Raspberry Pi to control this, which has 3.3v logic level outputs. I have previously used a 74HC125 to convert 3.3v logic to 5v logic, but this is only a 4 channel device, so instead of using 4 of these, is there an IC available that will allow me to use 2 or even 1 to drive the relay board.
The 74HC125 is labeled as a "Quad Buffer/Line Driver". I have found the 74HC541 which is similarly labeled as a "Octal Buffer/Line Driver", which I think seems like a good fit.
