pxi-6229 3.3v logic

[Steve_Block]

Can the PXI-6229 card interface with 3.3V logic even though it is a 5V card? If not, what is the best type of buffer to use?

Dear Steve Block,

thank you so much for your post on our webforum. For digital inputs the card sees a logical 0 with voltages from 0 - 0.8V. Voltages from 2.2 till 5.25V will be seen as a logical 1. Please let me know if you have any further questions,

Best regards,

What is the best way to buffer the 6229 card if I want to drive a 3.3V circuit and I'm concerned about damaging it?
