Re: Interfacing 3.3 Volt Logic sensors with CRIO

We are using the Sparkfun 3 sensor board found at the followinghttp://www.sparkfun.com/products/10724

We soldered our logic bus analyzer a TXB0104 to a breakout board. We are 100% sure we have it wired correctly however we could never pass any single through it.

The bus is running at the default digital sidecar frequency which I believe is 400Khz?

We are thinking the 3.3v logic may not be able to trigger the CRIO high level.
