RF Link Receiver questions

Hello, I have a question about the RFLink 434 MHz receiver.

It’s a 5V part, but to use it with a 3v3 micro, I need to convert. Can I use the 74AHCT125 for this? I have a bunch of them for my LED’s, but it also works to convert from 5V to 3v3 if you power it from 3v3. Since the data is one direction, this should be OK, but I would like to ask.

Thank you.

You should be OK without a logic level converter on these, but it won’t hurt to use one if you want to play it safe. :slight_smile:
